Best ResponseYou've already chosen the best response.1use the formula to find combinations : \[nCr= \frac{ n! }{ r! (nr)! }\] where n = the number you are choosing from (total number of crayons) r= the number you have to choose the (!) means factorials so for example 4! is 4x3x2x1

Best ResponseYou've already chosen the best response.1you will be able to determine the number of ways the colors can be used in pairs. after you determine that now use that as the total number (n) and r =9 since its 9 different areas

Best ResponseYou've already chosen the best response.1its 15 colors and you choose 2 , therefore 15C2= 105 that gives you how many ways you can use those 15 colors in pairs. but the problem is asking you how many ways you can use all those colors to color 9 areas
