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 fourth row, second column: N(female and Wednesday) = 3,011.
P(female and Wednesday) =
$\frac{N(\text{female and Wednesday})}{N(S)}=\frac{3,011}{75,330}\approx0.040\lt0.05.$
It is unusual for a fatality to occur on Wednesday and involve a female driver.
