To understand this problem, we need to first break it down. Assuming the tables are round, we can notice that this is a circular arrangement question.
We first need to assign five from a group of 10 people to a table. Since we don't care who appears on that table, we can use the notation:
However, since they are not distinct tables, then we would have overcounted by a factor of 2!, since there are two tables. Thus, the total number of ways to assign the tables is:
Now, we need to consider the total number of ways to arrange the people in each table. Since they are circular, then each table can be arranged in 4! ways.
