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.
