Answer
$P = \frac{8}{13}$
$= 0.62$ or $62$%
Work Step by Step
Picture cards: 12 cards
(Jack, Queen and King $\times$ Diamonds, Clubs, Hearts and Spades $= 3 \times 4 = 12$)
Black cards: 20 cards
(Ace, 2, 3, 4, 5, 6, 7, 8, 9 and 10 $\times$ Clubs and Spades $= 10 \times 2 = 20$)
1. Add up the number of picture and black cards:
$= 12 + 20$
$= 32$
2. Find the probability
Let $P =$ probability of selecting a black card or picture card
$P = \frac{32}{52}$
$= \frac{8}{13}$
$= 0.62$ or $62$%
