29% of college students say they use credit cards because of the rewards programs. You randomly select 10 college students and ask each to name a 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 programs is
(a) exactly two
Ans: binompdf(10,0.29,2) = 0.2444
------
(b) more than two
Ans: 1 - binomcdf(10,0.29,1) = 0.59010.79
----------------------
(c) between two and five inclusive.
Ans: binomcdf(10,0.29,5) - binomcdf(10,0.29,1) = 0.7941
