Suppose that the number of inquiries arriving at a certain interactive system follows a Poisson distribution with arrival rate of 12 inquiries per minute. Find the probability of 10 inquiries arriving
(a) in a 1-minute interval
(b) in a 3-minute interval
(a) X ~ Poisson(mean = 12). Calculate Pr(X = 10) using the usual pmf.

If you need more help, please show what you've done and say where you are stuck.
Didn't I just do this here?
Or is this a double post?
You did. Thread closed.
