The first student can be any one of 12. For each of those . . .
The second student can be any one of 11.
So there are (12 x 11) = 132 different ways that a pair can be formed from the 12 students.
But for every pair, there's another one that's exactly identical to it . . . Betsy and Joann is exactly
the same pair as Joann and Betsy.
So the number of different pairs is half of the number of ways they can be picked, (132/2) = 66 different pairs.
