Suppose that X is a geometric random variable, with parameter p = 0.45. Round to 2 decimal places. a) What is the value of E(X)? [a] b) What is the value of Var(X)? [b] Determine the value of the following probability statements. Round to 4 decimal places. c) P(X = 3) = [c] d) P(X = 5) = [d] Suppose that X is a geometric random variable, with parameter p = 0.35. Round to 4 decimal places. a) P(X = 3) = [a] b) P(X < 3) = [b] c) P(X > 4) = [c] {Hint: Compliments would be useful here} Suppose that X is a binomial random variable, with parameters p = 0.07 and n = 15. Round to 4 decimal places. a) P(X < 2) = [a] b) P(1 < < 5) = [b] c) P(X>x) = [c]
