Question

What is the probability of pulling a queen or a black 3 out of a standard deck of cards?

Answer 1

`(3)/(26)` of pulling a queen or a black 3.

Explanation:

Since there's 52 cards in an average deck and there's 4 queens, divide 52 with 4 and you'll get 13, so that means it's a
`(1)/(13)` chance of getting a queen.

Also because there's 4 "3"s and 50% of those cards are black (clubs and spades), divide 52 with 2 and you'll get a
`(1)/(26)` chance of getting a black 3.

Add both quotients to a common denominator of 52 and you will end up with 6/52. Then simplify the sum.

You should end up with
`(3)/(26)`.
