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 33 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 88 percent probability. What is the probability of you making it home for the holidays?

0.9604 = 96.04% probability of you making it home for the holidays

Step-by-step explanation:

We have these following probabilities:

100 - 33 = 67% probability of the flight happening.

In the 33%, that is, when the flight does not happen, there is an 88% probability that you get the ride with Walter.

What is the probability of you making it home for the holidays?

0.67 + 0.88*0.33 = 0.9604

0.9604 = 96.04% probability of you making it home for the holidays

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
