प्रश्न
One card is drawn from a well-shuffled deck of 52 cards. Find the probability of getting a jack of hearts.
उत्तर
Let E5 be the event of getting a jack of hearts.
Number of favourable outcomes = 1
∴ P(getting a jack of hearts) = P(E5) = `("Number of outcomes favourable to" E_5)/"Number of all possible outcomes"`
`= 1/52`
Thus, the probability of getting a jack of hearts is `1/52`.
