Question

From a well shuffled deck of 52 cards one card is drawn at random.find the probability of getting a 1.a red card 2.a 10 of black card 3.a face card?

Answer 1

Total posibility = 52 (a pack have 52 cards)

1). red cards
favourable events = 26 (a pack contains 26 red cards)

Probability (red card)=26/54 = 1/2 = 0.50

2). 10 of black card
favourable events = 2 (there are two 10 of black card in deck)

Probability (10 of black) = 2/54 = 1/26

3). a face card
favourable events = 12 ( 4kings + 4queens + 4jack)

Probability (face card) = 12/52 = 3/13
