Here's a way to think about it:
You choose one of three doors A B or C
Say the prize is behind C.
If you choose A, door B will be gotten rid of and if you then switch you win.
If you choose B, door A will be gotten rid of and if you then switch you win.
If you choose C, one of the other doors will be gotten rid of and if you switch you lose.
So out of three possibilities, 2 of them make you win.
So switching is the sensible option...
