What is the probability you would spin a number less than 10 and then a number in green?

The number of possible solutions of a polynomial can be found by looking

7x+8y=-18, 4x-9y=-3 solve the system of equations

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.
