Question
One card is drawn from a well-shuffled deck of 52 cards. Find the probability of getting a spade.
Solution
Total number of outcomes = 52
Let E6 be the event of getting a spade.
Number of favourable outcomes = 13
∴ P(getting a spade) = P(E6) = `("Number of outcomes favourable to" E_6)/"Number of all possible outcomes"`
`=13/52 = 1/4`
Thus, the probability of getting a spade is `1/4`.
