A2 B1 C3............one correct

A2 B3 C1............none correct

A3 B1 C2............none correct

A3 B2 C1............one correct

There are only 3!=6 possibilities.

There is no chance of getting exactly 2 correct and 1 wrong,

since if 2 are correctly matched, the 3rd will automatically be correctly matched.
