Question

In a deck of 52 cards, what is the probability of getting

(i) an even number card
(ii) black ace card.

Answer 1

Total no. of cards $=52$

(i) There are $5$ even numbered cards in one suit.

Therefore , total no. of even cards $=5\times 4=20$

P (getting an even number card) $=\frac{20}{52}=\frac{5}{13}$

(ii) There are $2$ black ace cards in a deck of cards ie one of Spade and one of Clubs

P (getting a black ace card) $=\frac{2}{52}=\frac{1}{26}$
