Question

from a well shuffled pack of playing cards black jacks, black kings and black aces are removed. a card is drawn. find the probability of a black card

Answer 1

Total number of cards in a deck = 52

Total number of cards removed = 2 + 2 + 2 = 6 black cards

Total number of cards left = 52 - 6 = 46

Find the probability of getting a black card;

⇒ Number of black card = 26 - 6(removed cards) = 20 cards

⇒ P(black card) = $\frac{20}{46}$= $\frac{10}{13}$
