A group of labels is classified by two properties

Let \(A\) be the set of plain labels, and let \(B\) be the set of bordered labels

The universe \(S\) contains 32 items. Each item is equally likely to be selected when a probability is requested

The Venn diagram shows the count in each disjoint region

Venn diagram in universe S with set A for plain items and set B for bordered items. A-only region is labelled 6; B-only region is labelled 5; shared region is labelled 8; region outside both sets is labelled 13.Splainbordered65813
