Two packs of card are thoroughly mixed and shuffled and two cards are drawn at random, one after the other. What is the probability that both of them are jack?

1/13
2/13
7/1339
1/169

Correct Answer: 7/1339

Explanation:

Total number of cards = 104
Total number of jacks = 8
∴ Probability for the jack in first draw = 8/104
and probability for the jack in second draw = 7/103
Since, both are independence events.
∴ Required probability = 8/104 x 7/103 = 7/1339
