Question

from a well shuffled deck of 52 playing cards, one card is drawn at random then the probability that card is a black jack

Answer 1

The possible outcomes are:
1. The Spade of Jack
2.The Club of Jack

Therefore the Probability of getting a black Jack will be 2/52 ,that is, 1/26

Answer 2

There are 26 black cards out of which there are 2 jacks.

Let A denote event of getting black jack.

Let S be the sample space.

n(S) = 52

n(A) = 2

P(A) = n(A) / n(S)

P(A) = 1/26

Hope it helps :)
