Asked Oct 16, 2019

A researcher is interested in conducting a mail survey. He finds out that there is a 40% response rate to such surveys. If a survey is mailed to 5 people, what is the probability that all respond?

-Binomial Distribution

Step 1

The probability that all respond is obtained below:

Here, the response rate is considered as a success, 40%, that is *p* = 0.40. The not responses is considered as a failure, 60% (100% – 60%) of that is *q* = 0.60.

Therefore, the distribution is binomial distribution with sample size 5 and probability of success 0.40. That is, *X*~ Binomial (5, 0.40).

The formula for the probability of binomial distribution is
