Question: A discrete random variable, X, has the probability distribution: A discrete random variable, Y, has the probability distribution: a. Find G x (t). b. Find

A discrete random variable, X, has the probability distribution:

1 3 P(X = x) 0.2 0.5 0.3


A discrete random variable, Y, has the probability distribution:


a. Find Gx(t).

b. Find Gy(t)

Hence, given that X and Y are independent:

c. Find Gx+y(t)
