A card is drawn from a deck of 52 cards. What is the probability that this card is an Ace or a Queen or a Spade or a Diamond?

13 spades 13 diamonds (2 of these are queens 2 are aces)

there are 2 more aces and 2 more queens

13 + 13 + 2 + 2 / 52

30/52

15/26

Hi Guest,

Let's use casework.

1. Ace

Since there are 4, it is 4/52

2. Queen

Since there are 4, it is 4/52

3. Spade

Since there are 13 and 2 overlap, it is 13-2/52

4. Diamond

Same as spade. 13-2/52

Adding gets us 2/13+11/26 which is 15/26
