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.

Q: What is the number of different ways that 2 out of 12 students can volunteer to organize a class party?

The number of students is discrete. There is no number of students between 4 and 5.

That depends on if the variable "number of students" is dependent on something else. For example, if the number of students is dependent on the time of year, then it is charted along the y-axis. If the number of students is independent, and the school's yearly expenses are dependent on the number of students, than the number of students should be tracked by the x-axis.
