Two cards are drawn one by one at random from a deck of 52 playing car

1.	Two cards are drawn one by one at random from a deck of 52 playing cards. What is the – probability Of getting two jacks if (i) the first card is replaced before the second card is drawn (ii) the first card is not replaced before the second card is draw?
Answer» n(S) = 52; P(J) = 4/52 (i) P(JJ) = (4/52) x (4/52) = (1/13) x (1/13) = 1/169 (ii) P(JJ) = (4/52) x (3/51) = (1/13) x (1/17) = 1/221

Answer»

n(S) = 52; P(J) = 4/52

(i) P(JJ) = (4/52) x (4/52) = (1/13) x (1/13) = 1/169

(ii) P(JJ) = (4/52) x (3/51) = (1/13) x (1/17) = 1/221
