The number of customers received by a drive-through pharmacy on Saturday mornings between 8:00 AM and 9:00 AM has a Poisson distribution with λ (Lambda) equal to 1.4. What is the probability of getting at least 2 customers between 8:00 am and 9:00 am in the morning?

Respuesta :

Answer:

0.4082

Step-by-step explanation:

Given that the number of customers received by a drive-through pharmacy on Saturday mornings between 8:00 AM and 9:00 AM has a Poisson distribution with λ (Lambda) equal to 1.4.

X has Poisson mean=1.4

the probability of getting at least 2 customers between 8:00 am and 9:00 am in the morning

=[tex]P(X\geq 2)\\=0.4082[/tex]

Required probability = 0.4082
