Question
A friend who lives in Los Angeles makes frequent consulting trips to Washington, D.C.; 60% of the time she travels on airline # 1, 20% of the time on airline
on airline # 3. For airline #1, flights are late into D.C. 40% of the time and late into L.A. 15% of the time. For airline #2, these
percentages are 35% and 10%. If we learn that on a particular trip she arrived late at exactly one of the two destinations,
and # 3? Assume that the chance of a late arrival in L.A. is unaffected by what happens on the flight to D.C. [Hint:
second-generation branches labeled, respectively, 0 late, 1 late, and 2 late.] (Round your answers to four decimal
