Question

A community college has 150 word processors. The probability that any one of them will require repair on a given day is 0.025.

To find the probability that exactly 25 of the word processors will require repair, one will use what type of probability distribution?
-Normal distribution
-Poisson distribution
-Binomial distribution
-None of these choices.

Answer 1

Binomial distribution

Explanation:

For each word processor, there are only two possible outcomes. Either it is going to require repair, or it is not. This means that we solve this problem using the binomial probability distribution.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, with p probability and X can only have two outcomes.

The corret answer is

Binomial distribution
