Math Problem Statement
22% 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. Question content area bottom Part 1 (a) P(2)equals 0.298 (Round to the nearest thousandth as needed.) Part 2 (b) P(xgreater than2)equals enter your response here (Round to the nearest thousandth as needed.)
