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.
About these worksheets
Students learn to count the number of possible combinations that can be made from a set of choices. Using organized lists and systematic counting strategies, these worksheets develop combinatorial thinking and logical reasoning skills.
Identifying Combination Amounts
- Count how many different pairs or groups can be made from a set of choices.
- Use organized lists or tables to make sure every combination is counted once.
- Tell the difference between combinations (order doesn’t matter) and different orders of the same items.
- Add up the number of possibilities from different groups to find a total number of combinations.
