Total number of possibilities are 72 possibilities ( 8*9) (shirts * pants) No. of combinations are not allowed are 6 possibilities (2 * 3) ( 2 shirts and 3 pants) Therefor (72 – 6) , 66 combinations are possible. IMO B

Barbara has 8 shirts and 9 pants she doesn’t wear 2 specific shirts with 3 specific pants This means, ideally she has 6 shirts and 6 pants to chose from. The combination in this case would be 6x6 = 36 Whatz the OA ?

whenever you have a negative connonation... prefer the 1 - x approach to solve. over here we see the "doesn’t" so (8*9 - 2*3) = 72-6 = 66 B is the answer
