Three airlines serve a Srinagar. Airline βAmiraβ has 50% of all the scheduled flights,
airline βBiyasβ has 30%, and airline βchinarβ has the remaining 20%. Their on-time rates
are 80%, 65%, and 40%, respectively. Part 1) Draw the Probability tree diagram. (Note: You may use any software for this, like
MS paint, MS office, etc.)
