When rolling a number cube, what is the probability of rolling a number greater than 2?

A. 1/4

B. 1/2

C. 2/3

D. 5/6

Answer 1

Note that a cube has 6 sides, and that the numbers on the face is 1 - 6.

The probability of rolling a number less than 3. Let "x" be the number:

x < 3

All numbers that fit the category is 1 & 2. Divide the part (2) from the whole (6):

2/6 = 1/3

B. 1/3 is your answer.

Note that a cube has 6 sides, and that the numbers on the face is 1 - 6.

The probability of rolling a number greater than 2. Let "y" be the number:

y > 2

All numbers that fit into the category is 3, 4, 5, & 6. Divide the part (4) from the whole (6):

4/6 = 2/3

C. 2/3 is your answer.
