प्रश्न
Which of the following cannot be the probability of an event?
37%
उत्तर
We know that probability of an event E is 0 ≤ P(E) ≤ 1
Since `0 ≤ 37% = (37/100) ≤ 1`
Therefore, 37% can be a probability of an event.

A card is drawn from a well-shuffled pack of 52 playing cards. Find the probability of the event, the card drawn is a red card.
Solution:
Suppose ‘S’ is sample space.
∴ n(S) = 52
Event A: Card drawn is a red card.
∴ Total red cards = `square` hearts + 13 diamonds
∴ n(A) = `square`
∴ p(A) = `square/("n"("s"))` ....formula
∴ p(A) = `26/52`
∴ p(A) = `square`
