Assume that a procedure yields a binomial distribution with a trial repeated nequals30 times. Use the binomial probability formula to find the probability of xequals5 successes given the probability pequalsone fifth of success on a single trial. Round to three decimal places.

Step-by-step explanation:

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

In which

And p is the probability of X happening.

In this problem, we have that:

Use the binomial probability formula to find the probability of xequals5 successes given the probability pequalsone fifth of success on a single trial.

This is P(X = 5).

answer: a.   one is a factor of every whole number since every number is divisible by itself.
