Dovator [93]

Answer:

The value is $P(X = 3) = 0.1804$

Step-by-step explanation:

From the question we are told that

The number of customer that enter the tellers every 5 minutes is $\lambda = 2$

Generally the probability that exactly three customers enter the queue in a randomly selected five-minute period is mathematically represented as

$P(X = 3) = \frac{e^{- \lambda} * \lambda^{3}}{3!}$

=> $P(X = 3) = \frac{e^{- 2} * \lambda^{3}}{3!}$

=> $P(X = 3) = 0.1804$
