Answer
$P(victim~and~the~offender~from~different~race)=\frac{1102}{7285}\approx0.1513$
Work Step by Step
$P(both~same~race)=\frac{6183}{7285}\approx0.8487$
The events "victim and the offender from different race" is the complement of "both same race".
$P(victim~and~the~offender~from~different~race)=1-P(both~same~race)=1-\frac{6183}{7285}=\frac{7285}{7285}-\frac{6183}{7285}=\frac{1102}{7285}\approx0.1513$
