- Let S={1,2,3,4} be a sample space with P(x)=kx where x is a member of S, and k is a constant. Compute E(S).Let (S, P) be the sample space with S = (1, 2, 3, ..., 10) and P (a) = 1/10 for all a ES. For this sample space, define the random variables X and Y by #2. X(s) = 25 and Y(s) = s a. Evaluate P (X< 10). b. Evaluate P (Y < 10).3. An integer is randomly chosen from the set 1, 2,..., 100. If this integer is divisible by 2 we let Y = 0, and if it is not divisible by 2 but is divisible by 3 then Y = 1. We let Y = 2 in all other cases. Find mean and variance of Y.
