Question
Five cards − the ten, jack, queen, king and ace of diamonds are well shuffled with their faces downwards. One card is then picked up at random. What is the probability that the drawn card is the queeen?
Solution
Total number of cards = 5.
Number of queens = 1.
∴ P(getting a queen) = `("Number of favourable outcomes")/"Number of all possible outcomes"`
`=1/5`
Thus, the probability that the drawn card is the queen is `1/5`.
