# Poisson Distribution with hourly rate

I have one question on probability,Which need the clear explanation

1. The number of customers appears at the ticket counter of PVR theatre at a rate of 120 per hour. Find the probability that during a given minute (i) No customer appear. (ii) At least two customers appear.

Please Say whether it comes under the poisson, if so what would be the mean value.

Yes, it looks like you might be expected to use the Poisson distribution here, perhaps with a rate measured in customers per minute. Can you figure out the arrival rate in customers per minute from the given information? –  Dilip Sarwate Nov 26 '12 at 12:53
@ Dilip Sarwate Thanks for commenting, This much only the data is available for this. any way to solve it –  Sudharsanan Nov 26 '12 at 12:57
If customers arrive at the ticket counter at an average rate of 120 per minute, what would you say the average rate of arrivals per minute? –  Dilip Sarwate Nov 26 '12 at 13:04
