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 8.
उत्तर
The number of possible outcomes = 6 × 6 = 36
The outcomes favourable to the event the sum of the two number is 8 = E = {(2, 6),(3, 5),(4, 4),(5, 3),(6, 2)}`
The number of outcomes favourable to E = n(E) = 5
Hence, `P(E) = (n(E))/(n(S)) = 5/36`
