Say we have a random sample of n = 15 online customers from a large population of customers to a popular online auction site. with p = 0.07 of the population proportion making a purchase, what is the probability of selecting exactly two customers who actually make a purchase in the random sample?

0.9171

Step-by-step explanation:

Binomial distribution formula to find the probability of success in x trials:-

, where n is the sample size and p is the population proportion for each trial.

Given : n= 15 ; p= 0.07

Then , the customers who actually make a purchase in the random sample is given by :-

Hence, the probability of selecting exactly two customers who actually make a purchase in the random sample = 0.9171
