Answer:
Step-by-step explanation:
Given that customers arrat a service window according to a poisson process with an average of 0.2 per minute
=  12 per hour.
a)  the probability that the time between two successive arrivals is less than 6 minutes
= For one hour more than 60/6 =10 customers arrive. 
P(X>10) = 0.6528
b) Prob that there will be exactly three arrivals during a given 10-minute period
P(x=3) for average 2
= 0.1804
