Problem 1. The time interval between the arrivals of successive planes at a certain airport is measured by a random variable X with probability density function -2/5 5e f(x) = 0, a >0 x < 0 where x is the time (in minutes) between the arrivals of randomly selected pair of successive planes. (1) What is the probability that two successive planes selected at random will arrive within 5 minutes of one another? (2) What is the probability that two successive airplanes arrive more than 6 minutes apart? (3) If Tony arrive at the airport just in time to see a plane landing, how long would he expect to wait for the next arrival.?
Rework problem 16 in section 4.2 of your text, involving drawing markers from a box of markers with ink and markers without ink. Assume that the box contains 12 markers: 9 that contain ink and 3 that do not contain ink. A sample of 6 markers is selected and a random variable Y is defined as the number of markers selected which do not have ink. Find the probability density function. Be certain to list the values of Y in ascending order.
