A card is drawn from a well-shuffled pack of 2 cards. Find the probability of getting (i) a red face card, (ii) a black king.

Answer :

Total numbers of elementary events are: 52

(i) Let E be the event of getting a red face card


Then, the numbers of favourable outcomes are: 6


Being 2 red cards of jack, 2 red cards of queen and 2 red cards of King


P (red card) = P (E) = 6/52 = 3/26


(ii) Let E be the event of getting a black king


Then, the numbers of favourable outcomes are: 2


Being only 2 card of king are of black colour in pack of 52


P (black king) = P (E) = 2/52 = 1/26
