Question

Assume the random variable X has a binomial distribution with the given probability of obtaining a success. Find the following probability, given the number of trials and the probability of obtaining a success. Round your answer to four decimal places.

P(X<2), n=5 p=0.3

Answer 1

Solution :

According to binomial probability law, probability of occurrence of exactly x successes in n trials is given by,

Where, p is probability of success.

We have to find P(X < 2).

We have, n = 5 and p = 0.3
