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 processor, there is only two possible outcomes. Eithey they will require repair, or they will not. This means that we solve this problem using the binomial probability distribution.

Binomial probability distribution

Probability of exactly x sucesses on n repeated trials, with p probability.
