PX = Y = X x (1−p)x−1p(1−q)x−1q = X x (1−p)(1−q)x−1 pq Recall that from page 31, for geometric random variables, we have the identity PX ≥ i = X∞ n=i (1−p)n−1p = (1−p)i−1 (1) So, we obtain PX = Y = pq pq −pq (b) What is Emax(X,Y)?. P(X = 1) = 3/8 ;.

P(X>5) = P(X=6 or X=7 or X=8 ) " " = P(X=6)P(X=7)P(X=8 ) " " = 0105 " " = 08 Alternatively P(X>5) = 1P(X. P(X>m) = (1 p)m Using this, we can now compute the conditional probability P(X>m njX>m) = P((X>m n) \(X>m)) P(X>m) = P(X>m n) P(X>m) Since (X>m n) \(X>m) (X>m n) = (1 p)mn (1 p)m = (1 p)n = P(X>n) This is exactly what we wanted to show This property is called memoryless because even knowing that.

Probability distribution definition and tables In probability and statistics distribution is a characteristic of a random variable, describes the probability of the random variable in each value Each distribution has a certain probability density function and probability distribution function.

If P(x) had an irreducible cubic factor q(x) in kx, then P(x) = 0 would have a root in a cubic extension K of k Since K k = 3, the eld Khas p3 elements, and jK j= p3 1 By Lagrange, the order of any element of K is a divisor of p 3 1, but 7 divides neither 3 1 = 26 = 5 mod 7. P(X=0) = 1/4 P(X=1) = 1/2 P(X=2) = 1/4 Draw pmf All possible outcomes should be covered by the random variable, hence the sum should add to one Note that you could define any number of random variables on an experiment Ex In a game, which consists of flipping two coins, you start with 1$ On each flip, if.

PX(x)=P(X = x)= M x N −M n−x N n for x=0, 1, 2, 3,···,n and x ≤ M, and n − x ≤ N − M (4) For this discrete distribution we compute the cumulative density by adding up the appropriate termsof the probability massfunction F(0) = p(0) F(1) = p(0) p(1) F(2) = p(0) p(1) p(2) F(3) = p(0) p(1) p(2) px(3) F(n)=p(0) p(1) p(2) p(3) ··· p(n) (5). In Example 321, the probability that the random variable \(X\) equals 1, \(P(X=1)\), is referred to as the probability mass function of \(X\) evaluated at 1In other words, the specific value 1 of the random variable \(X\) is associated with the probability. I = (PAT) is the mathematical notation of a formula put forward to describe the impact of human activity on the environment I = P × A x T The expression equates human impact on the environment to a function of three factors population (P), affluence (A) and technology (T).

P x Pr(X = x,Y = y) = Pr(X = x), likewise P x Pr(X = x,Y = y) = Pr(Y = y) So, EX Y = X x xPr(X = x) X y yPr(Y = y) = EXEY Notice that EX works just like a mean;. Homework 9 (Math/Stats 425, Winter 13) Due Tuesday April 23, in class 1 The joint probability mass function of X and Y is given by p(1,1) = 1/8 p(1,2) = 1/4. P(X = 3) = 1/8 ;.

P(x > 2) = 11/16 = 6875 Because 2 is the center event and because of the symmetry of a binomial distribution, this probability is the same as P(x 2) or problem 3 Applications.

P(X = 0) = 1/8 ;.

Given random variables,, , that are defined on a probability space, the joint probability distribution for ,, is a probability distribution that gives the probability that each of ,, falls in any particular range or discrete set of values specified for that variable In the case of only two random variables, this is called a bivariate distribution, but the concept generalizes to any. P(X < 1) = P(X = 0) P(X = 1) = 025 050 = 075 Like a probability distribution, a cumulative probability distribution can be represented by a table or an equation In the table below, the cumulative probability refers to the probability than the random variable X is less than or equal to x. P(x) of degree (at most) d such that p(xi)=yi for 1 •i •d 1 Let us consider what these two properties say in the case thatd =1 A graph of a linear (degree1) polynomial y =a1xa0 is a line Property 1 says that if a line is not the xaxis (ie if the polynomial is not y =0), then.

P(X i) = Probability X i = All Possible Outcomes This formula shows that for every value of X in a group of numbers, we have to multiply every value of x by the probability of that number occurs, by doing this we can calculate expected value. The latest tweets from @p_x_i_s_. PX = x = x 1 n xY 2 k=0 (1 k=n) p b) Find the limit as n !.

In fact we can think of it as being the population mean (as opposed to the sample mean) The variance is the expectation of (X −EX)2 Var(X) = X x p(x)(x−EX)2 1.

G(p),x = g′(p)p,x = − i~g′(p) In either case, fand gmay depend on other operators which commute with both xand p Thus, the formulae generalize immediately to multidimensional systems (ie systems with a set of xcoordinates, xi) xi,G(p) = i~ ∂G ∂pi pi,F(x) = − i~ ∂F ∂xi where we use the commutation relations xi,xj. Posterior Predictive Distribution I Recall that for a fixed value of θ, our data X follow the distribution p(Xθ) I However, the true value of θ is uncertain, so we should average over the possible values of θ to get a better idea of the distribution of X I Before taking the sample, the uncertainty in θ is represented by the prior distribution p(θ). Then p = P(X = 1) = P(A) is the probability that the event A occurs For example, if you flip a coin once and let A = {coin lands heads}, then for X = I{A}, X = 1 if the coin lands heads, and X = 0 if it lands tails Because of this elementary and intuitive coinflipping example, a Bernoulli rv is sometimes referred to as a coin flip, where p is.

Answer (i) deg p (x) = deg q (x) We know the formula, Dividend = Divisor x quotient Remainder p(x) = g(x)×q(x)r(x) So here the degree of quotient will be equal to degree of dividend when the divisor is constant Let us assume the division of 4x2 by 2 Here, p(x)=4x2. Let’s say that x represents birds on a lake, and so P(x) specifies ducks, and Q(x) specifies geese ∀x P(x) ∨∀x Q(x) says that for the birds on the lake, either all of them are ducks, or else all of them are geese But in this situation, the lake.

To disprove ∀x P(x) find a counterexample – some c such that ¬P(c) – works because this implies ∃x ¬P(x) which is equivalent to ¬∀ x P(x) proofs • Formal proofs follow simple welldefined rules and should be easy to check – In the same way that code should be easy to execute • English proofs correspond to those rules but are. Some moments are E X i = np i, VarX i = np i (1 − p i), and CovX i Xj = − np i p j The multinomial distribution generalizes the binomial Consider an experiment having a total of r possible outcomes, and let the corresponding probabilities be p 1, , p r, respectively Now perform n independent replications of the experiment and let Xi record the total number of times that the i. Y y) Continuous case If X and Y are continuous random variables with joint density f(x;y) over the range a;b c;d then the joint cdf is given by the double integral F(x;y) = Z y Z x f(u;v)dudv c a To recover the joint pdf, we di erentiate the joint cdf Because there are two variables we need to use partial derivatives.

P X ( x) = P ( X = x) = ∑ y j ∈ R Y P ( X = x, Y = y j) law of total probablity = ∑ y j ∈ R Y P X Y ( x, y j) Here, we call P X ( x) the marginal PMF of X Similarly, we can find the marginal PMF of Y as P Y ( Y) = ∑ x i ∈ R X P X Y ( x i, y) Marginal PMFs of X and Y. F(x;y) = P(X x;. Feb 28, 17 · The notation P (xy) means P (x) given event y has occurred, this notation is used in conditional probability There are two cases if x and y are dependent or if x and y are independent Case 1) P (xy) = P (x&y)/P (y) Case 2) P (xy) = P (x) Share edited Feb.

Mar 06, 17 · P(X>5) = 08 The standard notation is to use a lower case letter to represent an actual event, and an upper case letter for the Random Variable used to measure the probability of the event occurring Thus the correct table would be And then;. P(X = a) = P(a ≤ X ≤ a) = R a a f(x) dx = 0 • A discrete random variable does not have a density function, since if a is a possible value of a discrete RV X, we have P(X = a) > 0 • Random variables can be partly continuous and partly discrete 2. So let's make a formula In our previous example, how can we get the values 1, 3, 3 and 1 ?.

(a) Find P(X Y ≤ 1) (b) Find the cdf and pdf of Z = X Y Since X and Y are independent, we know that f(x,y) = fX(x)fY (y) = ˆ 2x·2y if 0 ≤ x ≤ 1 and 0 ≤ y ≤ 1 0 otherwise We start (as always!) by drawing the support set, which is a unit square in this case (See below, left) 4. The mean of the distribution is equal to 0*04 = 80, and the variance is equal to 0*04*06 = 48 The standard deviation is the square root of the variance, 693 The probability that more than half of the voters in the sample support candidate A is equal to the probability that X is greater than 100, which is equal to 1 P(X< 100). 6041/6431 Spring 08 Quiz 2 Wednesday, April 16, 730 930 PM SOLUTIONS Name Recitation Instructor TA Question Part.
