Question 657841: how many ways can a student select 2 electives from a possible choice of 10 electives?

You take the possible number of choices, in this case 10, and you multiply it by the number of places, in this case,2, subtracting 1 from the possible number of choices each time. So, your set up would look like 10*9 to get the answer of 90.
