P Xy Mhx A

Let $p$ be an odd prime and $G = \langle x,y x^p = y^p = (xy)^p = 1 \rangle$ I want to show that $G$ is infinite and wonder if there is a good way to prove this.

If X and Y are independent, then E(es(XY )) = E(esXesY) = E(esX)E(esY), and we conclude that the mgf of an independent sum is the product of the individual mgf’s Sometimes to stress the particular rv X, we write M X(s) Then the above independence property can be concisely expressed as M XY (s) = M X(s)M Y (s), when X and Y are independent Remark 11 For a given distribution, M(s.

P(X = x;Y = y) P(Y = y) = fX;Y (x;y) fY (y) This looks identical to the formula in the continuous case, but it is really a di erent formula In the above fX;Y and fY are pmf’s;. To see a counterexample, consider P(x,y) = \person x is in location y" Then 8x9yP(x;y) says \Everyone is located somewhere", while 9x8yP(x;y) says \Someone is located everywhere" These clearly don’t mean the same thing!.
