Airplanes approaching the runway for landing are required to stay within the localizer (a certain distance left and right of the runway). When an airplane deviates from the localizer, it is sometimes referred to as an exceedence. Consider one airline at a small airport with six daily arrivals and an exceedence rate of 7%. a) Find the probability that on one day no planes have an exceedence. (2 points) b) Find the probability that at least 1 plane exceeds the localizer. (3 points) c) What is the expected number of planes to exceed the localizer on any given day? (2 points) d) What is the variance for the number of planes to exceed the localizer on any given day? (3 points)

1- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis.2- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in the first question?
