7-3 Sample Spaces and Events - University of Colorado Boulder
... Sample spaces and events: The sample space (S) is the collection of basic outcomes of an experiment. Example : Rolling a die Sample space: { 1, 2, 3, 4, 5, 6} An event E is defined to be any subset of S (including the empty set and the sample space S). Event E is a simple event if it contains only o ...

... number of men to get the number who don't walk, then divide this by the total number of men: (109,059 25,146)/(109,059). Or, you could calculate the probability that a man walks for exercise and then subtract it from 1 to get the probability that he does not walk for exercise: 1 - (25,146/109,059). ...
