Assume our class data applies to the whole school, with a total of 2200 students.
1. A student is seen vandalizing a school bathroom. The eyewitness who saw this said that it was a
male student, who had brown hair, and was wearing blue jeans and a dark shirt. What is the
probability of a student fitting into these 4 categories of class evidence?
2. Out of the entire student population, how many total students would likely fit this description?
