**Problem 5:**A service organization on campus needs a group of six students from their organization’s membership of 123 students to serve as program attendants at graduation. In how many ways can the attendants be chosen?*Explanation:* To solve this, we use combinations since the order of selection does not matter. The formula for combinations is:\[\binom{n}{r} = \frac{n!}{r!(n-r)!}\]Where \( n \) is the total number of items to choose from, and \( r \) is the number of items to choose. Apply this to find the number of ways to choose six students from 123.

It is given that there are totally 123 students to serve as program attendants at graduation.
