Suppose that the number of calls coming per minute into an airline reservation center follows a poisson distribution. assume that the mean is 3 calls per minute. the probability that at least two calls are received in a given two-minute period is

0.9826

Step-by-step explanation:

Given : Mean :

For two minutes period the new mean would be :

The formula to calculate the Poisson distribution is given by :_

Then ,the required probability is given by :-

Hence, the probability that at least two calls are received in a given two-minute period is 0.9826.

on a coordinate grid, point a is at (−4.0, −2.4) and point b is at (4.0, −2.4). point b is a reflection of point a across the –axis. input either a lowercase x or i think is the right awnser
