36%of college students say they use credit cards because of the rewards program. You randomly select 10 college students and ask each to name the reason he or she uses credit cards.

Find the probability that the number of college students who say they use credit cards because of the rewards program is

(a) exactlytwo, (b) more than two,and(c) between two and five inclusive. If convenient, use technology to find the probabilities.

(a)P(2)=_____?(Round to the nearest thousandth as needed.)

(b)P(x>2)=____?(Round to the nearest thousandth as needed.)

(c)P(2x5)=_____?(Round to the nearest thousandth as needed.)

A doctor gives a patient a 60% chance of surviving bypass surgery after a heart attack. If the patient survives thesurgery, then the patient has a 55% chance that the heart damage will heal.

Find the probability that the patient survives the surgery and the heart damage heals. The probability is ____?. (Type an integer or adecimal.)
