Answer
Probability of card being a picture card = $\frac{3}{13}$
Work Step by Step
Total number of outcomes when dealing a card from card deck = 52
Total number of favorable outcomes when dealt card is a picture card = 12 ( 4 - jack, 4 - queen, 4- king)
When a card is dealt from 52 cards, the probability of card being a picture card = $\frac{12}{52}$
= $\frac{3}{13}$
