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.

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints
