The number of parking tickets issued in a certain city on

any given weekday has a Poisson distribution with

parameter m 5 50.

ACalculate the approximate probability that between

35 and 70 tickets are given out on a particular day.

BCalculate the approximate probability that the total

number of tickets given out during a 5-day week is

between 225 and 275.

CUse software to obtain the exact probabilities in (a)

and (b) and compare to their approximations.
