Question

A card is chosen at random from a deck of 52 cards. It is replaced, and a second card is chosen. What is the probability that both cards chosen are jacks?

a)1/26
b)1/13
c)1/169
d)2/13

Answer 1

C

Explanation:

4/52 for the first card since there are 4 jacks in a deck of 52 cards * 4/52 for the second card since you replaced the jack last time and there are still 4 jacks in a deck of 52 cards.

Answer 2

c) 1/169.

Explanation:

There are 4 jacks in a pack of cards .

So Probability (Jack) = 4/52 = 1/13.

and the Probability (2 Jacks) = 1/13 * 1/13

= 1/169.
