Answer to Question #344488 in Statistics and Probability for add

Question

Three airlines serve a Srinagar. Airline ‘Amira’ has 50% of all the scheduled flights,

airline ‘Biyas’ has 30%, and airline ‘chinar’ 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.)

Answer 1

Event A represents that scheduled flights for Airline Amira.

Event B represents that scheduled flights for Airline Biyas.

The event C represents that scheduled flights for Airline Chinar.

The event E represents that flight left in on time.

The prior probabilities are:

P(A)=0.50

P(B)=0.30

P(C)=0.20

The posterior probabilities are:

P(E|A)=0.80

P(E|B)=0.65

P(E|C)=0.40

So, the probability diagram:
