The following graphic shows: a discrete random variable X (its possible values) its PMF (associated likelihood for X takes a specific value), and a derived new random variable Y through a transformation Y = g ( X ) Note: The use of equivalent events or sets in the following calculations P{Y=10} = P{X=1} = 0.15 due to the fact { Y=10} Ù {X=1} P{Y=50} = P{X=6}+P{X=7}+P{X=8} = 0.3 due to {Y=50} Ù {X=6, or X=7, or X=8}

Figure 2.2 (p. 90) The PMF of Y and the relative frequencies found in two sample runs of voltpower (100). Note that in each run the relative frequencies are close to (but not exactly equal to) the corresponding PMF.
