Lesson Worksheet: Probability Mathematics
In this worksheet, we will practice describing probability using words like “certain,” “likely,” “unlikely,” and “impossible.”
A spinner is divided into 10 equal sectors numbered 1 through 10. If the spinner is spun, is it certain, likely, unlikely, or impossible that it lands on a number less than 4?
If the spinner is spun once, determine whether it is certain, likely, unlikely, or impossible that the pointer stops on a number that is a multiple of 3.
What is the probability of rolling a number which is greater than 6 on a fair die?
There are 15 letter tiles in a bag: six tiles are labeled S, eight tiles are labeled R, and one is labeled M. Which of the following describes how likely it is to choose the letter M?
A bag contains 35 marbles, 34 of which are blue. If a marble is picked out at random, what is the likelihood of it being blue?
When this spinner is spun, which of the following describes the probability that the arrow lands on a sector that is NOT yellow?
- DEqually likely that it happens or does not happen
If this spinner is spun, which of the following describes the probability that the pointer lands on blue?
- BIt is equally likely for it to happen or not happen.
If this spinner is spun once, it is certain, likely, unlikely, or impossible that it stops on an even number?
Which outcome is least likely when spinning the arrow on this spinner?
Which outcome is most likely when spinning the arrow on this spinner?
