Work Step by Step

The sample space: 75,330 drivers involved in fatal crashes in the United States in 2009. So, N(S) = 75,330. According to the cell in the first row, first column: N(male and Sunday) = 8,222. P(male and Sunday) = $\frac{N(\text{male and Sunday})}{N(S)}=\frac{8,222}{75,330}=\frac{4,111}{37,665}=0.109$
