Medical research has shown that a certain type of chemotherapy is successful 70% of the time when used to treat skin cancer. Suppose five skin cancer patients are treated with this type of chemotherapy and let x equal the number of successful cures out of the five. The probability distribution for the number x of successful cures out of five is given in the table. X 1 2 3 4 5 P(X) .002 .029 .132 .309 360 .168 Questions: a) Out of five cancer patients treated with this type of chemotherapy, compute the probability that there are: more than 3 successful cures less than 4 successful cures. b) Compute P (3
