Question

what is the probability that the card drawn from a stack of 52 cards is a face card or a black card?​

Answer 1

Answer:  8/13

Step-by-step explanation:

There are 52 cards in a deck.

26 cards are black -->  P(Black) = 26/52

Face cards are J, Q, K.  There are 12 face cards -->  P(Face) = 12/52

6 Face cards are black --> P(both) = 6/52

Face card     or      Black card     -    both Face card & Black

      $\dfrac{26}{52}$             +            $\dfrac{12}{52}$            -            $\dfrac{6}{52}$                             $=\dfrac{32}{52}$

$\dfrac{32}{52}\div \dfrac{4}{4}=\dfrac{8}{13}$
