About these worksheets
These worksheets introduce basic probability concepts through hands-on scenarios. Students determine the likelihood of selecting specific items from a set, identify most and least probable outcomes, and calculate probability using spinners, dice, and object arrays. Activities build an intuitive understanding of chance and likelihood.
Basic Probability
- Find the probability of an event by counting favorable outcomes out of all possible outcomes.
- Read a spinner or die and list the possible outcomes in the sample space.
- Compare which event is more likely, less likely, or equally likely based on the numbers of outcomes.
- Use pictures or arrays of objects to calculate the chance of picking a certain item at random.
Determining Spinner Probability
- Look at a spinner and decide which value is most likely to be landed on.
- Look at a spinner and decide which value is least likely to be landed on.
- Tell when two or more outcomes are equally likely by comparing the sizes or counts of sections.
- Match probability words like most likely, least likely, and equally likely to what the spinner shows.
