is flying from Boston to Denver with a connection in Chicago. The probability her first flight leaves on time is 0.250.25. If the flight is on time, the probability that her luggage will make the connecting flight is 0.80.8, but if the flight is delayed, the probability that the luggage will make it is only 0.550.55. Complete parts a) and b). a) Are the flight leaving on time and the luggage making it to Denver with her independent events? b) What is the probability that her luggage arrives in Denver with her?
