Find the probability exactly 3 successes in 6 trials of a binomial experiment in which the probability of success if 50%. round to the nearest tenth of a percent.

Hence, the probability of exactly 3 successes in 6 trials of a binomial experiment round to the nearest tenth of a percent is:

31.2%

Step-by-step explanation:

The probability of getting exactly k successes in n trials is given by the probability mass function:

Where p denotes the probability of success.

We are given that  the probability of success if 50%.

i.e.

also form the question we have:

k=3 and n=6.

Hence the probability of exactly 3 successes in 6 trials is:

Hence,

In percentage the probability will be:

answer: a.

step-by-step explanation: the answer is a. because, you need to converge the fractions to find a solution.
