Answer

$0.00484$

Work Step by Step

We know that $probability=\frac{number \ of \ good \ outcomes}{number\ of\ all\ outcomes}$, therefore $P(not \ guilty)=\frac{58+14}{392+58+564+14}=\frac{72}{1028}\approx0.07003$. By using the multiplication rule: $\frac{72}{1028}\times\frac{71}{1027}=\frac{1278}{263939}\approx0.00484$.
