Question 940212: Let X be the number of successes in six independent trials of a binomial experiment in which the probability of success is
p =
4
5
.
Find the following probabilities. (Round your answers to four decimal places.)
(a)
P(X = 5)

Correct: Your answer is correct.

(b)
P(3 ≤ X ≤ 5)

You can put this solution on YOUR website!
p(success) = 4/5 ???, n = 6
P(x = 5) = binompdf(6, .8, 5)
P(3 ≤ x ≤ 5) = binomcdf(6, .8, 5) - binomcdf(6, .8, 2)
