Suppose that about 9.2% of the population is left-handed. A 200-seat school auditorium has been built with 15 “lefty seats,” seats that have the built-in desk on the left rather than the right arm of the chair. In a class of 120 students, what is the probability that there will not be enough seats for the left-handed students? Explain how you arrived at your answer.

    A lecture hall has 200 seats with folding arm tablets, 26 of which are designed for left-handers. The typical size of classes that meet there is 186 , and we can assume that about 15 % of students are left-handed. Use a Normal approximation to find the probability that a right-handed student in one of these classes is forced to use a lefty arm tablet. The probability is %.
