<math> A \backslash B </math> represents ''difference'', that is, <math>A</math> ''but not'' <math>B</math>. For example, we may be interested in the event of drawing the queen of spades from a deck of cards. This can be expressed as the event of drawing a queen, but not drawing a queen of hearts, diamonds or clubs.<br> | <math> A \backslash B </math> represents ''difference'', that is, <math>A</math> ''but not'' <math>B</math>.
