प्रश्न
Two dice are thrown at the same time. Find the probability that the sum of the two numbers appearing on the top of the dice is 13.
उत्तर
The number of possible outcomes = 6 × 6 = 36
There is no outcome favourable to the event E = the sum of two numbers is 13.
n(E) = 0
Hence, `P(E) = (n(E))/(n(S)) = 0/36`

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`
