Question

There are 20 students on the school's council .A Special homecoming dance committee will be formed by randomly selecting 6 students from council. How many possible committees can be formed?

Answer 1

Order is irrelevant, as this is a committee

therefore, use the combination formula nCr = n! / ( r! (n-r)! ) where n is the total # of people being picked from (20) and r is the number of people being picked at a time (6)
