SB 7.4 probability w/o replacement

Question

4. Find the probability of drawing an ace and a jack when two cards are drawn (without replacement) from a standard deck of cards.

 

a. 16/2607

b. 4/663

c. 1/221

d. 1/169

 

Answer 1

the probability is the probability you draw ace at the first draw (4/52) multiplied by the probability you draw jack at the second draw (4/51) since there are no replacement  

 

P = (4/52)*(4/51)=16/2652 = 4/663

 

The correct answer is option b
