Answer:
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:
