If a random geometry student is chosen, what is the chance (in percent) the student is a freshman or sophomore? Show how you can use the Addition Rule to answer this question. What was unusual about using the Addition Rule to answer this question?
The unusual part is that the probability of
and (the overlap) was . of the geometry students perform in band and perform in chorus. There is a chance that a geometry student performs in either band or chorus. What is the probability a geometry student performs both in band and in chorus?
Use the Addition Rule again but this time you will need to solve the equation.
