Venn Diagrams into Bar Diagrams · Investigations A–C

Choose the matching investigation context. First break each three-way Venn diagram into three bar diagrams — one bar per group — by filling in every bar section yourself. Each bar's parts (only, pair-only, all three) must add up to that group's total. Then select the requested regions and calculate the probability. “Or” includes students in both groups.

Context:

First, convert the Venn diagram: type the number of students for every bar section. Each bar's parts must add up to the group total shown beside it. Once the bars are built, click a bar section or a Venn region to select it while answering — matching sections light up in both diagrams.
