A new drug cures 75% of the patients to whom it is administered. It is given to 28 patients. Find the probabilities that among these patients, the following results occur. Use the normal distribution approximation to the binomial distribution. (a) Exactly 20 are cured. (b) All are cured. (c) No one is cured. (d) 13 or fewer are cured.

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?

When a patient complains to the doctor about a certain set of symptoms, the doctor diagnoses the patient with Condition A 15% of the time. If a patient with these symptoms is diagnosed with Condition A, he or she is diagnosed with Condition B 70% of the time. A patient with these symptoms that is not diagnosed with Condition A is diagnosed with Condition B 10% of the time. What is the probability that a patient with this set of symptoms will be diagnosed with at least one of these conditions?
