Answer
Age: At least 18.
Race: White.
Sex: Male.
Work Step by Step
From (a), (b), (c): $N(S)=7285$
- Age of victim:
$N(Less~than~18)=124+619+39=782$
$N(At~least~18)=290+5628+480=6398$
$N(Unknown)=4+80+21=105$
So: $P(At~least~18)=\frac{6398}{7285}\gt P(Less~than~18)=\frac{782}{7285}\gt P(Unknown)=\frac{105}{7285}$
- Race of victim:
$N(White)=3026+573+53+57=3709$
$N(Black)=208+3034+12+49=3303$
$N(Other)=54+28+97+7=186$
$N(Unknown)=30+27+4+26=87$
So: $P(White)=\frac{3709}{7285}\gt P(Black)=\frac{3303}{7285} \gt P(Other)=\frac{186}{7285}\gt P(Unknown)=\frac{87}{7285}$
- Sex of victim:
$N(Male)=4710+490+89=5289$
$N(Female)=1735+150+24=1909$
$N(Unknown)=50+11+26=87$
So: $P(Male)=\frac{5289}{7285}\gt P(Female)=\frac{1735}{7285}\gt P(Unknown)=\frac{87}{7285}$
