1. The problem statement, all variables and given/known data In how many ways can 8 different things be divided into groups of 5 and 3. 2. Relevant equations 3. The attempt at a solution I thought it be just be 8C5 X 8C3 but also might it be 8C5 x 3C3 since if you take 5 you only have 3 left to select from?
