Let a  and b denote a part above and below the specification, respectively.

 S  =  = {aaa { aaa,, aab aab,, aba aba,, abb abb,, baa baa,, bab bab,, bba bba,, bbb bbb}} 2-3.

Let a  denote an acceptable power supply.

Let f  Let  f , m , and c  denote a power supply that has a functional, minor, or cosmetic error, respectively.  S  =  = {a { a , f , m , c } 2-5.

Let y and n denote a web site that contains and does not contain banner ads.

The sample space is the set of all possible sequences of y and n  of length 24. An example outcome in the sample space is S  is S  =  = {yynnynyyynnynynnnnyynnyy { yynnynyyynnynynnnnyynnyy}. }. 2-7.

 S  is  is the sample space of 100 possible two digit integers.
