A friend who lives in Los Angeles makes frequent consulting trips to Washington, D.C.; 55% of the time she travels on airline #1 and the remaining 25% of the time on airline #2, and 20% of the tine on airline #3. For airline #1, flights are late into D.C. 30% of the time and late into L.A. 10% of the time. For airline #2, these percentages are 25% and 20%, whereas for airline #3 the percentages are 40% and 25%. If we learn that on a particular trip she arrived late at exactly one of the two destinations, what are the posterior probabilities of having flown on airlines #1, #2 and #37 Assume that the chance of a late arrival in L.A. is unaffected by what happens on the flight to D.C.
