Question

deeny chose two cards randomly from a deck. what is the probability of geeting a queen and a jack without replacement.

Answer 1

Explanation:

choose 2 cards randomly from a deck...P(queen)....no replacement...P(jack)

so there is 52 total cards in a deck......and there are 4 queens....so the probability of getting a queen is 4/52 reduces to 1/13

no replacement

so now there are 51 cards in the deck....and 4 jacks...so the probability of picking a jack is 4/51

the probability of both events happening is : 1/13 * 4/51 = 4/663 <==
