3.2 cars use the diesel pump every 2 hours.
a) Average number of cars arrival in one hour, =
3.2/2 = 1.6 cars/hour
Probability that 3 cars will arrive in one hour period, P(X=3) =
b)Average number of cars arrival in half an hour, =
3.2/4 = 0.8 cars/half hour
Probability that no cars will arrive in half hour period, P(X=0) =
c) Average number of cars arrival in one hour, =
3.2/2 = 1.6 cars/hour
Probability that 5 or more cars will arrive in half hour period, P(X>=5) = 1-P(X<5)
= 1 - [P(0)+P(1)+P(2)+P(3)+P(4)]
Either a rare event occurred or perhaps the long run average

Problem 15-1 Willow Brook National Bank operates a drive-up teller window that allows customers to complete bank transactions without getting out of their cars. On weekday mornings, arrivals to the drive-up teller window occur at random, with an arrival rate of 24 customers per hour or 0.4 customers per minute. What is the mean or expected number of customers that will arrive in a five-minute period? λ = per five minute period Assume that the Poisson probability distribution can be used...

The number of calls arriving at a switchboard from noon to 1
p.m. during the business days Monday through Friday is monitored
for six weeks (i.e. 30 days). Let X be defined as the number of
calls during that one-hour period. The relative frequency of calls
was recorded and reported as:
Values 5 6 8 9 10 11 12 13 14 15
Rel. Freq. 0.067 0.067 0.100 0.133 0.200 0.133 0.133 0.067 0.033

The Denver post reported that on average a large
shopping center had an incident of shoplifting caught by security
1.9 times every 4 hours. The shopping center is open from 10:00
a.m. to 9:00 p.m. (11 hours). Let r be the number of shoplifting
incidents caught by security in an 11 hour period during which the center is
open.
