Assume the random variable X has a binomial distribution with the given probability of obtaining a success. Find the following p
Verizon [17]

Answer:

P(X = 17) = 0.3002

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.

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

In which C_{n,x} is the number of different combinations of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

And p is the probability of X happening.

In this problem we have that:

n = 18, p = 0.9

We want P(X = 17). So

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

P(X = 17) = C_{18,17}.(0.9)^{17}.(0.1)^{1} = 0.3002

P(X = 17) = 0.3002
