Consider the following random experiment: A fair coin is tossed once. Here, the sample space hasonly two elements S = {H,T}. We define a sequence of random variables X1, X2, X3. . on this...sample space as follows:if s = H= (s)"XX,(s)if s = Ta. Are the X;'s independent?b. Find the PMF and CDF of X,, Fx. (x) for n = 1,2, 3, .
