A binomial probability experiment is conducted with given parameters. Compute the probability of x successes in the n independent trials of the experiment.

N=15, p=0.2,×=4

P(X = 4) = 0.1876

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 is the number of different combinations of x objects from a set of n elements, given by the following formula.

And p is the probability of X happening.

In this question:

We want P(X = 4). So
