What is 2 choose 3?
Answer
2 choose 3 is
0
Order doesn't matter, no repeats: you can't choose 3 items from 2, so there are 0 ways.
3 > 2 → C(2, 3) = 0
If order matters (permutations): P(2, 3) = 0 too.
Row sum: 22 = 4 — all subsets of 2 items.
k = 3 is past the end of row 2.

Why is 2 choose 3 zero?
You can't pick 3 different items when there are only 2, so there are no ways at all and the answer is 0, not an error. Often the numbers are swapped: 3 choose 2 = 3.
How many ways are there if order matters?
Still none: 3 different items can't be taken from 2 in any order, so P(2, 3) = 0 too.
