Question

The rate of new home buying customers arriving is one every three hours. What is the probability at
least 8 customers arrive in 18 hours? (Assume Poisson Distribution)
0.8472
0.3333
0.1528
0.7440

Expert Solution

Step 1

Given:

Customer arriving per every three hours = 1

Average customer arriving per every 18 hours $λ$ = 6

Formula Used:

$P (X = x) = \frac{e^{- λ} λ^{x}}{x!}, X = 0, 1, 2, . . .$
