Statistical technology

"28% 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."

HA! "If convenient, use technology to find the probabilities."

Yeah, and "if not convenient to use technology, please proceed in spending enormous amounts of time wracking your brain for abstract mathematical concepts and formulas. Once those formulas have been produced, use entire sheets of paper to complete ridiculously long problems and hope that you didn't make a stupid mistake somewhere in the process. But again, only if you find technology inconvenient."

When the formula looks like this: you can be SURE I'll be using technology thankyouverymuch.
