#### Work Step by Step

P(event)=$\frac{numberoffavorableoutcomes}{numberofpossibleoutcomes}$ There are 100 possible outcomes because there are 100 total responses. There are 15 favorable responses so 15 is the number of favorable outcomes. P(event)=$\frac{numberoffavorableoutcomes}{numberofpossibleoutcomes}$ P(trade school)=$\frac{15}{100}$ P(trade school)=0.15 or 15%
