प्रश्न
A card is drawn at random from a pack of 52 cards. Find the probability that the card drawn is black and a king
उत्तर
Let S denote the sample space.
Then, n(S) = 52
Let E3 = event of drawing black and a king
There are two cards: a black card and a king, i.e. a black king.
i.e. n (E3) = 2C1 = 2
