Question
One card is drawn from a well-shuffled deck of 52 cards. Find the probability of getting a queen of black suit.
Solution
Total number of outcomes = 52
Let E4 be the event of getting a queen of black suit.
Number of favourable outcomes = 2
∴ P(getting a queen of black suit) = P(E4) = `("Number of outcomes favourable to" E_4)/"Number of all possible outcomes"`
`=2/52 = 1/26`
Thus, the probability of getting a queen of black suit is `1/26`.
