प्रश्न
A card is drawn at random from a pack of 52 cards. Find the probability that the card drawn is not a black card.
उत्तर
Let S denote the sample space.
Then, n(S) = 52
Let E12 = event of drawing a non-black card
We know that there are 26 non-black cards, i.e. 13 diamonds and 13 hearts.
Then n (E12) = 26
