Answer: binomial probability
Explanation:
A binomial probability indicates to the probability of having exactly x successes on n repeated trials in an particular binomial experiment which has only two possible outcomes.
If the probability of success on an single trial is b (which does not change) , then , the probability of failure will be (1-b) .
The binomial probability for success in x trials out of n trials is given by :-
