"not" - -Let A = Bob wears a black suit. Let B = Bob wears black shoes. We can now use this table to define some important categories in probability. In the table below, "not A" is illustrated in orange. Remember A = "Bob wears a black suit." "Not A " is Bob wears a blue or brown suit. The color of the shoes is irrelevant. In our Bob example, "not B " is not wearing black shoes. This is again illustrated in orange in the table below. "not" venn diagram - -"Not A " in our real-world example is "Americans employed last year as something other than factory workers." Teacher, postal worker, librarian, business woman, etc. all belong to "not A ." Note that it includes people in category B who are not in A , such as librarians who were injured by falling bookshelves. However, it is best not to explicitly consider B when trying to decide if something is not A . It's enough to ask "is this person someone who was employed last year in a type of factory work?". If not, she belongs to "not A ." In the diagram below, the orange shaded area represents all the elements in "not A ."
