Answer
$P(victim~is~a~white~female)=\frac{1883}{14,990}\approx0.1256$
Work Step by Step
The sample space: $5067+1883+6+6294+1126+1+301+105+0+131+42+34=14,990$ murder victims. That is:
$N(S)=14,990$
Now, $N(victim~is~a~white~female)=1883$
$P(victim~is~a~white~female)=\frac{N(victim~is~a~white~female)}{N(S)}=\frac{1883}{14,990}\approx0.1256$
