A card is picked from a deck of 52 cards. Find the probability of getting a black ace or a red queen.

In a standard deck of 52 cards, we have:

• 2 black Aces with probability 2/52 = 1/26 using our fraction simplifier
• 2 red Queens with probability 2/52 = 1/26 using our fraction simplifier

The problems asks for P(Red Queen Or Black Ace). Or means we add, so we have:
P(Red Queen Or Black Ace) = P(Red Queen) + P(Black Ace)
P(Red Queen Or P Black Ace) = 1/26 + 1/26
P(Red Queen Or P Black Ace) = 2/26
P(Red Queen Or P Black Ace) = 1/13 using our fraction simplifier
