Question

A dice is thrown once. Find the probability of getting : (i) an even number (ii) a number between 3 and 8 (iii) an even number or a multiple of 3.

KnowledgeBoat · Accepted Answer

In a single throw of dice, the possible outcomes are {1, 2, 3, 4, 5, 6}. ∴ No. of possible outcomes = 6. (i) Out of 1, 2, 3, 4, 5, 6, the even numbers are 2, 4, 6. ∴ No. of favourable outcomes = 3. P(getting an even number) = . Hence, the probability of getting an even number = . (ii) Out of 1, 2, 3, 4, 5, 6, the numbers between 3 and 8 are 4, 5, 6. ∴ No. of favourable outcomes = 3. P(getting a number between 3 and 8) = . Hence, the probability of getting a number between 3 and 8 = . (iii) Out of 1, 2, 3, 4, 5, 6, the numbers that are either an even number or a multiple of 3 are 2, 3, 4, 6. ∴ No. of favourable outcomes = 4. P(getting either an even number or a multiple of 3) = . Hence, the probability of getting either an even number or a multiple of 3 = .
