Q2.1 2 Points What is the probability that he succeeds for the first time on his 5th try? That is, what is P(X = 5)? Write your answer in 5 decimals place, including the leading zero (e.g 0.00312) Hint: Which zoo element is the waiting time until the first success? Q2.2 1 Point What is E[X]? Give your answer to 2 decimal places (e.g. 3.12) (Hint: You can plug into a nice formula if you can identify the zoo element!) Q2.3 1 Point What is Var(X)? Give your answer to 2 decimal places (e.g. 3.12) (Hint: You can plug into a nice formula if you can identify the zoo element!)
