## Algebra 1

P(event)=$\frac{numberoffavorableoutcomes}{numberofpossibleoutcomes}$ There are 100 possible outcomes because there are 100 total responses. There are 85 favorable responses because trade school-total responses=85 responses, so 85 is the number of favorable outcomes. P(event)=$\frac{numberoffavorableoutcomes}{numberofpossibleoutcomes}$ P( not trade school)=$\frac{85}{100}$ P( not trade school)=0.85 or 85%
