Question

what is the probability on selecting on a black
Jack from a deck of card​

Answer 1

Number of black jacks in a deck of cards = 2

Total number of cards in a deck of cards = 52

P(black jack) = 2/52 = 1/26.

Answer 2

To find :

The probability of selecting a black

Jack from a deck of cards.

Solution :

• Number of cards in a deck of cards = 52

• There are 4 types of cards in a deck of cards - spades, clubs, hearts, and diamonds, out of which spades and clubs are black in colour.

• Number of Jack in each type of card = 1

=> Number of black Jacks in a deck of cards = Jack of spades + Jack of clubs = 1 + 1 = 2

• Now, probability of drawing a black Jack from a deck of cards = Number of black Jacks / Total number of cards in a deck

=> P = 2 / 52

=> P = 1 / 26

∴ The probability of selecting a black Jack from a deck of cards is 1 / 26.
