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≥14), n=18, p=0.8

Sagot :

The probability is 0.2153.

What is Probability?

It is a branch of mathematics that deals with the occurrence of a random event.

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

[tex]^{n}C_x* P^{x}* (1-p)^{n-x}[/tex]

n=18, p=0.8

So,

[tex]^{18}C_{14}* 0.8^{14}* (1-0.8)^{18-14}[/tex]

=0.2153

Hence, the probability is 0.2153.
