Answer
$P(postterm~and~3000~to~3999~grams)=\frac{175,221}{4,305,340}=0.04070$
Work Step by Step
The sample space: $4,305,340$ babies born in 2007. So, $N(S)=4,305,340$
According to the cell in the fourth row, third column: $N(postterm~and~3000~to~3999~grams)=175,221$
Using the Empirical Approach (page 258):
$P(postterm~and~3000~to~3999~grams)=\frac{N(postterm~and~3000~to~3999~grams)}{N(S)}=\frac{175,221}{4,305,340}=0.04070$
