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 < Median )=0.5

(Enter your answer to one integer and two decimal places. For example, if your answer is "8.72", you would write 8.72). Do not round.
