10.2.1 Histograms

Histograms can be used to show these distributions graphically.

Cumulative distributions can be used to estimate the probability of an event. For example, if in the graph above we want to know how many pizzas are delivered within 25 minutes, we could read 10 (approx.) every week off the graph.

there are typically 10 to 20 divisions in a histogram

percentages can be used on the right axis, in place of counts.
