Number A is correct.

Step-by-step explanation:

So, it is asking you what question it is answering.

1. See what it is telling you.

"  Atlanta's Hartsfield-Jackson International Airport is the busiest airport in the world. On average there are 2,500 arrivals and departures each day. "

2. Next read the answers.

" a. How many airplanes arrive and depart the airport per hour?

b. What is the probability that there are exactly 100 arrivals and departures in one hour?

c. What is the probability that there are at most 100 arrivals and departures in one hour? "

3. Pick the most reasonable answer.

Now, I might not be right, for I am not a teacher. But this is how I learned how to solve problems like these.

a is the correct

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23
