# Question

Consider the binomial experiment with n = 300 and p = 0.2.

a. Set up, but do not evaluate, the probability expression for 75 or fewer successes in the 300 trials.

b. Use a computer or calculator to find P(x < 75) using the binomial probability function.

c. Use a computer or calculator to find P(x < 75) using the normal approximation.

d. Compare the answers in parts b and c.

FYI Use the cumulative probability commands.
