प्रश्न
A card is drawn at random from a well-shuffled deck of 52 cards. Find the probability of getting a king or an ace.
उत्तर
Total number of all possible outcomes= 52
Total number of kings = 4
Total number of aces = 4
Let E be the event of getting a king or an ace card.
Then, the favourable outcomes = 4 + 4 = 8
∴ P( getting a king or an ace) = P (E) = `8/52 = 2/13`
