Etwo precalculus sections at a high school. mr. abel's class has 14 girls and 8 boys, while mr. bonitz's class has 10 girls and 12 boys. if a precalculus student chosen at random happens to be a girl, what is the probability she is from mr. abel's class?

There is a 58.3% chance that she is from Mr. Abel's class.

Given the fact that we know the person chosen is a girl, the chance is out of 24 because 10 + 14 = 24.

In Mr. Abel's class, there are 14 girls.

So the probability that a girl is from Mr. Abel's class is 14/24 or 58.3%.
