Solve the system of inequalities by graphing y> 2/5x+2 and y< -1/5x-1

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.

Combine the information in the problem and the chart using the average balance method to solve the problem.
