Question

You are thinking about the things that can go wrong on your trip home over the Thanksgiving break. You have booked a flight with US-Scareways. You know that in 28 percent of the cases the company has canceled the flight you were on. Should such a thing occur, there would be no other air travel option home for you. As a backup, your friend Walter has offered you a ride back. However, you know that Walter only has a seat in his car for you with 84 percent probability. What is the Probability of you making it home for the holidays

Answer 1

0.9552

Explanation:

Probability of making home can be made by either of the options :-

• Prob (Reach through flight) : 1 - prob (flight not cancelled) = 1 - 0.28 = 0.72
• Prob (Reach through car) : prob (flight cancelled & car seat is available) = 0.28 x 0.84 = 0.2352

So, probability of making out at home : Reach through flight or car = 0.72 + 0.2352 = 9.9552
