For example: RRRRBBBBBB = 4 red first then 6 blue and is one way they can be sorted. BRRRRBBBBB = 1 blue, 4 red, and 5 blue is another way they can be sorted.Give you answer as a whole number.

This  would be similar to  the number of identifiable  "words" that can formed using  4 R's  and 6 B's

 

So we have

 

(4 + 6)!           10!                   3628800                    

_______ =   ________  =     __________ =  210  identifiable "words"

4!  * 6!          24 * 720               17280
