Curves C1 and C2 are parametrized as follows: C1 is (x(t),y(t))=(t,0) for −1≤t≤1 and C2 is (x(t),y(t))=(cost, sint) for 0≤t≤π. Sketch, on a separate sheet of paper, the curves C1 and C2 with arrows showing their orientation.

33% 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) exactly two, (b) more than two, and (c) between two and five inclusive. if convenient, use technology to find the probabilities.
