The question asks how many ways 2 people can line up.
One will be in front, the other behind.
umm.. is it 2?
thank you! :)
You're welcome.
is it 3
It is actually only 2 ways: Person 1 can be in front and Person 2 behind, or Person 2 can be in front and Person 1 behind.
To find the number of ways in which 2 people can line up to buy tickets at the Downtown Theater, we can use the concept of permutations.
In this case, since there is only 1 ticket window, the order in which the people line up matters. Person A and Person B can line up in two possible ways:
1. Person A first, Person B second: represented as AB.
2. Person B first, Person A second: represented as BA.
Therefore, there are 2 ways in which 2 people can line up to buy tickets at the Downtown Theater.
