The probability that a student uses the Academic Resource Center on a regular basis is 0.26. In a group of 18 students, what is the probability that exactly 8 of them use the Academic Resource Center on a regular basis? Round your answer to 2 decimal places.

Answer 1

Find P(8).

n = 18
x = 8
p = 0.26

Use a binomial probability table or a calculator.

If you must do this by hand, here is a formula:

P(x) = (nCx)(p^x)[q^(n-x)]

I'll let you take it from here.
