Eight people are randomly sat at a round table. what is the probability the people are sitting in alphabetical order?

For circular arrangements like a round table, it is difficult to say where the sequence of people would start from. So we will fix the position for the person who is first in alphabetical order. Then we will arrange remaining seven people.

Total number of ways to arrange seven people would be (7 x 6 x 5 x 4 x 3 x 2 x 1) = 5,040 ways.

And there will be only 1 arrangement when all people are in alphabetical order.

So probability would be

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).
