प्रश्न
A card is drawn at random from a pack of 52 cards. Find the probability that the card drawn is a black king
उत्तर
Let S denote the sample space.
Then, n(S) = 52
Let E1 = event of drawing a black king
We know that the number of black kings is two: one for spade and one for club.
i.e. n (E1) = 2
