... the sample space is called a simple event. If S is the sample space and S = {s1 , s2 , … , sn } , then the simple events are {s1} , {s2 } , … , {sn } . If an experiment involves rolling a die, the sample space is S = {1, 2, 3, 4, 5, 6} and the simple events are {1} , {2} , {3} , {4} , {5} , and {6} ...
