Question
All red face cards are removed from a pack of playing cards. The remaining cards are well shuffled and then a card is drawn at random from them. Find the probability that the drawn card is a red card.
Solution
There are 6 red face cards. These are removed.
Thus, remaining number of cards = 52 − 6 = 46.
Number of red cards now = 26 − 6 = 20.
∴ P(getting a red card) = `("Number of favourable outcomes")/"Number of all possible outcomes"`
`= 20/46 = 10/23`
Thus, the probability that the drawn card is a red card is `10/23`.
