Answer = 12(C)5 - 3*9(C)4 - 6*9(C)3 - 9(C)2 12(C)5 represent the number of ways to select 5 things out of 12 things. 12(C)5 = total possible ways to select 5 out of 12 9(C)4 = total possible ways to select group such that only one from X,Y,Z must be there. so multiplied by 3 because 3 cases possible (X, Y, Z)+ other 4 people from 12-3=9 person 9(C)3 = total possible ways to select group such that only two from X,Y,Z must be there. so multiplied by 3 because 3 cases possible (XY, YZ, ZX)+ other 3 people from 12-3=9 person. 9(C)2= all X,Y,Z must be there. (from 12-3 =9 we need to take 2 more people) Answer = Total cases - Not desired case read less
