Vehicle arrivals at a certain intersection from 9-10 am have a poisson distribution = 70/hr. a berkeley te student counts arrivals at the intersection during this time period for a number of days. 1. write an exact expression for the probability that 75 or more vehicles will be counted on a particular day

0.2905

Step-by-step explanation:

Given that vehicle arrivals at a certain intersection from 9-10 am have a Poisson distribution = 70/hr.

Also given that A Berkeley TE student counts arrivals at the intersection during this time period for a number of days.

To find the probability for 75 or more vehicles

Let X be the no of vehicles

P(k events ) =

Hence here required probability=

=
