Weegy: 5! + 2! = 122 5! = 5 * 4 * 3 * 2 * 1 = 120; 2! = 2 * 1 = 2; 120 + 2 = 122

There are 20 students on the school's student council. A special homecoming dance committee is to be formed by randomly selecting 6 students from student council. How many possible committees can be formed?
720
38,760
27,907,200
(More) 3
To find the number of possible committees that can be formed, we need to use the formula for combinations. The formula for combinations is:
C(n , r) = (n!)/r!(n-r)
where n is the total number of items, and r is the number of items being chosen. In this case, there are 20 students on the student council, and we want to choose 6 students for the special homecoming dance committee. So, we have:
C(20,6) = (20!)/6!(20-6)! = (20!)/(6!14!)
Using a calculator, we can simplify this expression to:
C(20,6)=38,760
Therefore, there are 38,760 possible committees that can be formed from the 20 students on the student council. The answer is 38,760.
