Since the boxes are distinct (the question would be very different if they were indistinguishable) answer the two sub-questions: How many ways can $b$ blue balls be distributed in $n$ distinct boxes? How many ways can $r$ red balls be distributed in $n$ distinct boxes? Find the answer to your original question by using the answers to these two smaller questions and applying multiplication principle. – JMoravitz Dec 01 '16 at 06:33

The answer to that smaller question can be found in an earlier question here. – JMoravitz Dec 01 '16 at 06:39
