प्रश्न
A card is drawn from a well-shuffled pack of 52 cards. Find the probability of getting a red face card.
उत्तर
Favourable outcomes = 2red kings + 2red queens + 2red jack = 6
Total outcomes = 52
`P(E)="Number of outcomes favourable to E"/"Number of all possible outcomes"`
`=6/52`
`=3/26`
Thus, the probability of getting a red face card is `3/26`.
