In a deck of cards, there is a 3 in every suit...that's four 3's.
There are also a queen in every suit...that's four queens as well.
Therefore, there are 8 cards in the deck which are either 3 or queens.
8/52 is base probability. Reduce by dividing out a 4 from both terms.
P(drawing a 3 or queen) = 4/13
