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?
+36916 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
+874 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
