6!/2!*3! = 60.

6! because 6 letters can be arranged in 6! ways
/2!3! because 2 B's and 3C's - we would care less as to how they are arranged.

Also got 60 = 6! / 2*3!
Total possible outcomes: 6! of placing different letters
Since A repeats twice and C repeats thrice, divide answer by 2!*3! or 2*3!
