Probability

A card that is not a ten and not a diamond is drawn. (out of an ordinary deck of 52 cards)

For some reason, I am not coming up with the right answer. Can you work this out for me.. I keep getting 35/52...but I know that isn't right.

1. There are 12 types (number or face) that are not tens, and of the remaining 48 cards, 36 are not diamonds.

By subtracting all diamonds (13) and all tens (4) from 52, you double-counted the ten of diamonds.
