Find the probability of at least three successes in six trials of a binomial experiment in which the probability of success is 50%. round to the nearest tenth of a percent.

Step-by-step explanation:

If the probability of success is 50%, then p=0.5 and q=1-0.5=0.5.

At least three successes in six trials of a binomial experiment means that favorable are 3 successes, 4 successes, 5 successes and 6 successes.

1. 3 successes:

2. 4 successes:

3. 5 successes:

4. 6 successes:

Now, the probability of at least three successes in six trials of a binomial experiment is
