Question 3 10 pts Suppose that the number of customers (X) who enter a bank in a minute is a Poisson random variable. We know that: P(X = 0) = 0.5*P(X=1) (where * is the multiplication sign) Compute the probability that a customer will spend less than three minutes in the bank. (Enter your answer to two decimal places. For example, if your answer is "0.72", you would write 0.72). Do m round. Question 4 10 pts Suppose that the number of customers (X) who enter a bank in a minute is a Poisson random variable. We know that: P(X = 0) = 2*P(X=1) (where * is the multiplication sign) Let T be the time between customers arriving to the bank. Find the median time. Hint: P( T
