Question

What is the probability of pulling a diamond, or a jack, or a king, or a 5, or a 7, or a spade, or the 4 of hearts in a deck of cards?

Answer 1

diamond 13/52
jack 4/52*only two that are not spades or diamonds (already included) so ignore 2*
king 4/52*only two that are not spades or diamonds (already included) so ignore 2*
5 4/52*only two that are not spades or diamonds (already included) so ignore 2*
7 4/52 *only two that are not spades or diamonds (already included) so ignore 2*
spade 13/52
4 of hearts 1/52
(13+13+2+2+2+2+1)/52=35/52
