प्रश्न
One card is drawn from a well-shuffled deck of 52 cards. Find the probability of getting a face card.
उत्तर
Total number of outcomes = 52
Let E2 be the event of getting a face card.
Number of favourable outcomes = 12
∴ P(getting a face card) = P(E2) = `("Number of outcomes favourable to" E_2)/"Number of all possible outcomes"`
`= 12/52 = 3/13`
Thus, the probability of getting a face card is `3/13`.
