A card is drawn from a well-shuffled deck of 52 cards what is the probability of getting an ace

A card is drawn from a well-shuffled pack of 52 cards. Find the probability of getting:(ix) a non-ace

(x) non-face card of black colour

(ix) Let E be the event of getting a non ace card.

There will be 48 non ace cards.

Number of favourable outcomes = 48

P(E) = 48/52 = 24/26 = 12/13

Hence the probability of getting a non ace card is 12/13.

(x) Let E be the event of getting a non face card of black colour.

There will be 20 non face cards.

Number of favourable outcomes = 20

P(E) = 20/52 = 5/13

Hence the probability of getting a non face card of black colour is 5/13.
