Question 878580: A group of 5 entertainers will be selected from a group of 20 entertainers that includes "Small" and "Trout". In how many ways could the group of five include at least one of the entertainers "Small" and "Trout" ? I have tried setting it up as a combination and I just don't seem to be anywhere close to getting the correct answer. Please be specific in how to set up this problem for solving as I need to see the process in order to completely understand it for my final. THANK YOU Answer by ewatrrr(24785) (Show Source):
You can put this solution on YOUR website! "at least one" is a catch all opposite... of NONE
20C5 total ways (subtract NO small and NO trout)
Am assuming there is an equal number of small and trout(10each)
20C5 - (10C5)(10C0) - (10C5)(10C0)
