Student:_____________________Date:_____________________1.29% of college students say they use credit cards because of the rewards program. You randomly select 10 collegestudents and ask each to name the reason he or she uses credit cards. Find the probability that the number of collegestudents who say they use credit cards because of the rewards program is (a) exactly two, (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(2 ≤ x ≤ 5) =(Round to the nearest thousandth as needed.)Solution...
