a card selected from a deck of 52 cards what is the probability it is a black card or face card

Facts:

• Half the cards in the deck are black (26/52)
• There are 12 face cards (K, Q, J) in a deck (12/52)
• Black and Face = 6/52 (Duplicates from above)

P(Black or Face) = P(Black) + P(Face) - P(Black And Face)
P(Black or Face) = 26/52 + 12/52 - 6/52
P(Black or Face) = 32/52

We can simplify this. We use our fraction simplifier to get:
P(Black or Face) = 8/13
