Given
we are given a deck of cards.
Required
we need to find the probability of getting a queen or spade.
Explanation
here
number of queens in deck =4
and number of spades =13
Total number of cards in a deck is 52
Now probability of getting a queen or a spade is
[tex]\frac{4+13}{52}=\frac{17}{52}[/tex]which is the required probability.
