Assume, a drug is effective in 75% of all patients. If 12 patients are treated with this drug, what is the probability that it will be effective for at least 9 patients?
Joanna Q.
A medical researcher surveyed a large group of men and women about whether they take medicine as prescribed. Assume that, in a large population, the probability that a person will always take medicine as prescribed is 0.51. If 9 people are selected at random from the population, what is the probability that at least 5 of the people selected will always take medicine as prescribed? Support your answer.
