Consider a poisson distribution with an average of three customers per minute at a local grocery store. if x = the number of arrivals per minute, find the probability of more than 7 customers arriving within a minute.

0.0216

Step-by-step explanation:

Given : Average arrivals of customers at a local grocery store = 3 per minute

The Poisson distribution formula :-

, where is the mean of the distribution.

If X = the number of arrivals per minute, then the probability of more than 7 customers arriving within a minute will be :-

Hence, the probability of more than 7 customers arriving within a minute = 0.0216
