Question

Circle the correct statement: About 55% of small businesses in the United States have a website. You randomly select 10 small businesses. What is the probability that 4 of them have a website? This problem is an example of:

A) normal probability with n=10 and x=4 and u=.55

B) binomial probability with n=10 and x=4 and p=.55

C) standard normal distribution with n=10 and u=4 and o=.55

D) none of the above

* u= mean and o= standard deviation symbol

Answer 1

A binomial experiment is a statisticalexperiment that has the following properties: The experiment consists of n repeated trials. Each trial can result in just two possible outcomes. We call one of these outcomes a success and the other, a failure. The probability of success, denoted by P, and the probability of failure by q.

Since there is probabilitiy of success is 0.55.where n=10 and X=4.so the answer is given that

B) binomial probability with n=10 and x=4 and p=.55
