## ABSTRACT

Even when the events of an experiment involve numbers, it may be necessary to convert these numbers to new values which are more easily analyzed. For example, when a pair of fair dice are tossed, the fundamental event is the pair of faces facing upward when the dice come to rest. The original sample space

S

is then made up of pairs of numbers. It is convenient to convert these pairs into single number values. If the numbers on the faces of each pair are summed, a single number is obtained. The set of these numbers is the range space R. This process is shown in Table 8.2.
