Question 1166168: The number of members arriving at a gym follows a Poisson distribution with a mean of 2 members per minute.
(a) What is the probability that 3 members arrive in 30 seconds?
(b) Determine the probability (in percentage) that the lady at the front entrance can have a 2 minute uninterrupted coffee break?

Since this is proportional to time, this is the same as 6 members in a minute. The parameter is 2 in a minute
prob=e^(-2)*2^6/6!=0.0120
probability have 0 when the parameter is 2. This is e^(-2)=0.1353
