Answer:
Value of a is 0.667
Step-by-step explanation:
We are given the following in the question:
The rate of customer at an airport follows a Poisson distribution with

The normal approximation of Poisson distribution can be done in the following manner

Formula:
We have to find the value of a such that

A=9
B=11
C=12
D=15
THE LENGTH OF THE LARGEST POSSIBLE SIDE IS
or,9+11+12+15
or,47 answer
