Question

A number cube with faces labeled 1 to 8 is rolled once. The number rolled will be recorded as the outcome. Consider the following events. Event A: The number rolled is odd. Event B: The number rolled is less than 4 Give the outcomes for each of the following events.

Answer 1

Answer to A:

50%

Explanation for A:

We're looking for how many numbers are odd, so theres 1, 3, 5 ,7, four numbers.

We have a total of 8 numbers.

`(4)/(8) = 0.5`

To make any number a percent we move the point over to the right by two, which makes our final answer 50%

Answer to B:

37.5%

Explanation for B:

If the number is less than four, that means we need to find if it will roll the first three numbers. We, once again, have eight total possibilities

`(3)/(8) = 0.375`

0.375 can be turned into our final answer, 37.5%
