A structured worksheet on two-set and three-set Venn diagrams. Students start with a set-notation warm-up, then shade twelve two-set regions and six three-set regions, identify the eight disjoint regions of a three-set diagram, and finish with a contextual probability problem. Full solutions with correctly shaded diagrams included.
Students match set-notation expressions to shaded regions, progressing from simple (A∪B, A′) through compound ((A∩B)′, A′∪B′) to three-set expressions ((A∩B)\C, (A∪B)∩C′) and eight-region identification.
A real-world scenario asks students to complete a Venn diagram from given totals, find probabilities of union, intersection and complement events, compute a conditional probability, and shade and interpret a described region.
