An exam has 6 essay questions and 4 multiple choice questions. A student must select at least one essay question and at least one multiple choice question.
a. a student last quarter tried to calculate this result by 6 * 4 * 8, that is choosing one essay question, one mc question, and choosing a bonus question from the remaining 8 ?s. This does not count all of the possibilities. Give a specific example of a result that is not counted by this method.
b. how many options does a student have for selecting the three questions and designating one of them to be the bonus question?
I have been thinking about this one for a while...anyone able to point me in the right direction?
