Suppose that Bayanisthol, a new drug, is effective 40% of the time in clinical trials.
a) Calculate the probability that the new drug is effective exactly 9 or 10 times out of a sample of 30
people.
b) Determine the expected value number of trials that the new drug is effective in a sample of 30 people.
c) Calculate the probability that the new drug is effective forat most10 people out of a sample of 30 people. Round your answer to 4 decimal places. (Hint: Use the normal approximation.)
