Unformatted text preview: a. What is the pmf and b. What is the cdf c. Graph the cdf a. Possible values of M are {1,2,3,4,5,6} P(1) = P(M=1) = 1/36 P(2) =p(M=2) = p(2,1) + p(1,2) + p(2,2)= 3/36 P(3) = 5/36 P(4)= 7/36 P(5)= 9/36 P(6)= 11/36 b. Cdf is the summation of probabilities c. Graph is the function y= x 2 The expected value of a discrete r.v X is E(X)= ( ) x p x The variance is V(x)= (  ) ( ) x u 2p x Frequently used distribution P(1)= q P(0) = 1q E(X) = nq V(X)= nq(1q)...
