Answer» There are 4 Kings in a deck.(i) So the probability of drawing a king is 4/52if the card is replaced, then again the probability would be 4/52.so joint probability would be= (4/52)x(4/52)=1/169(ans)(ii) the probability of drawing a king out of 52 cards is 4/52.the probability of drawing a king out of 51 cards is (3/51)so joint probability is (4/52)x(3/51)=1/221(ans) |
