Question

A fair number cube is rolled. What is the probability that a number greater than 2 is rolled?

A 2/3
B 1/2
C 1/4
D 1/5

Answer 1

Answer: A.
`(2)/(3)`

Explanation:

Given : A fair number cube is rolled.

We know that the total number of faces with different numbers from 1 to 6 on a fair number cube =6

Numbers greater than 2 on cube = 3 , 4 , 5 , 6

Now, the probability that a number greater than 2 is rolled is given by :-

`(4)/(6)=(2)/(3)`

Hence, the probability that a number greater than 2 is rolled is
`(2)/(3)`.

Answer 2

3 ,4 ,5 ,6 are greater than 2

4/6 which is simplified to 2/3

Choice A
