DeGroot (3 rd ed. = section 5.11 or 4 th ed.), section 5.9: # 3, 5, 6 3. Here you are going to calculate some binomial probabilities. Look back to HW 5 to remember how to compute binomial probabilities in R. (a) The ASPC is booking a charter ﬂight to San Francisco for spring break. They assume that some students will oversleep on the day of departure and won’t make it to the ﬂight. As a result, they decide to sell more tickets for the ﬂight than seats on the airplane.
