Question

A spinner is divided into 10 equal sections numbered 1 through 10. If the arrow is spun once, what is the probability it will land on a number less than 3?

Answer 1

Well since your options are 3, 2, and 1 and you spin it once, the chances would be 3/10

Answer 2

First, you need to find all the numbers that are less than three.
2 < 3.
1 < 3.

These are two options out of ten, so in fraction form, it would be 2/10, or 1/5. 

If you were looking for the odds, the answer would be 2/8, or 1/4.
