Answer
$0.88$ or $88\%$
Work Step by Step
We know for a probability that
$P(\text{an event happens})=1-P(\text{an event does not happen})$
Note that $12 \%=0.12$.
Thus,
$P(\text{not cleared by an arrest})=1-P(\text{cleared by an arrest})=1-0.12=0.88$
Hence,
$P(\text{Not cleared by an arrest}) =0.88=88\%$
