Question

Suppose we want to choose 2 letter, without replacement, from the 3 lettersA, B, C.

How many ways can this be done, if the order of the choices is not relevant

Answer 1

only 3, A with B B with C and A with C, but if you can use the same 2 if reversed it would be 6, for it would be A with B, B with A, C with B, B with C, A with C, and C with A.
