In a single throw of a dice, find the probability of getting : (i) 5 (ii) 8 (iii) a number less than 8 (iv) a prime number.

In a single throw of a dice, the possible outcomes are {1, 2, 3, 4, 5, 6}. ∴ No. of possible outcomes = 6. (i) No. of favourable outcomes (for getting a 5) = 1 P(getting a 5) = . Hence, the probability of getting a 5 = . (ii) Since, no face as number 8 written on it, there is no outcome favourable to 8. ∴ No. of favourable outcomes = 0. P(getting a number 8) = = 0. Hence, the probability of getting 8 = 0. (iii) Out of 1, 2, 3, 4, 5, 6, the numbers less than 8 are 1, 2, 3, 4, 5 and 6. ∴ No. of favourable outcomes = 6. P(getting a number less than 8) = = 1. Hence, the probability of getting a number less than 8 = 1. (iv) Out of 1, 2, 3, 4, 5, 6, the prime numbers are 2, 3, 5. ∴ No. of favourable outcomes = 3. P(getting a prime number) = . Hence, the probability of getting a prime number = .
