Answer
We have less chance of going to prison if we say that we are guilty.
Work Step by Step
From exercise 2: $P(prison| guilty)=\frac{392}{956}\approx0.41004$
From exercise 3: $P(prison|not \ guilty)=\frac{58}{72}\approx0.80556$.
Therefore we have less chance of going to prison if we say that we are guilty.
