Work Step by Step

We know that $P\left(\text{an event happens}\right)=1-P\left(\text{an event doesn't happen}\right).$ Hence, here we have, (with $12\%=0.12$): $P(\text{not cleared by an arrest})=1-P(\text{cleared by an arrest})\\ P(\text{not cleared by an arrest})=1-0.12\\ P(\text{not cleared by an arrest})=0.88$
