Answer
See the picture.
Work Step by Step
Total:
$N=20+21+46+13=100$
Relative frequency of "0-14":
$P(0-14)=\frac{fr(0-14)}{N}=\frac{20}{100}=0.20$
Relative frequency of "15-29":
$P(15-29)=\frac{fr(15-29)}{N}=\frac{21}{100}=0.21$
Relative frequency of "30-64":
$P(30-64)=\frac{fr(30-64)}{N}=\frac{46}{100}=0.46$
Relative frequency of ">64":
$P(\gt64)=\frac{fr(\gt64)}{N}=\frac{13}{100}=0.13$
