GRE Math Review 4 Data Analysis - ETS Home

Events that cannot occur at the same time are said to be mutually exclusive. For example, if a 6 sided die is rolled once, the event of rolling an odd number and the event of rolling an even number are mutually exclusive. But rolling a 4 and rolling an even number are not mutually exclusive, since 4 is an outcome that is common to both events. ................
