Figure 10.1 The proportion of tosses of a coin that give a head changes as we make more tosses. Eventually,
however, the proportion approaches 0.5, the probability of a head. This figure shows the results of two trials of
5000 tosses each.

Figure 10.4 The probability model for the outcomes of a software random number generator, for Example
10.8. Compare the histogram of 10,000 actual outcomes with the uniform density curve that spreads probability
evenly between 0 and 1.
