# What is the probability of picking an ace or a queen?

In a standard deck of 52 cards, there are 4 aces and 4 queens, so the probability of picking an ace or queen is 8 in 52, or 2 in 13, or about 0.1538.

### If you draw a card from a standard deck of cards what is the probability of drawing a heart or an Ace?

The chance of picking a heart is 1/4 as there are four suits. The chance of picking an ace is 1/13, as there are 4 aces in a deck of 52. If I want the probability of drawing a heart of an ace, I can add these probabilities together, but I have double counted on possibility, the ace of hearts. So: Probability = 4/52 + 13/52 - 1/52 = 16/52 or 4/13 Probability = 0.308…
