Okay so you have 10 members. So you would go 10 divided by 3 that is equal to 9 with one left over.

that is the combination of 10 over 3, which is calculated as the quotient of factorials: n!/k!(n-k)! where n = 10 and k = 3: = 10!/3!(10 - 3)! = 10!/3!*7! = (10*9*8)/(3*2*1) = 720/6 = 120 therefore there a re 120 possible different groups
