Beads

How many ways can we thread 4 red, 5 blue and 6 yellow beads on the thread?

Result

n =  630630

Solution:

n=(4+5+6)!4! 5! 6!=630630n = \dfrac{ (4+5+6)! }{ 4! \cdot \ 5! \cdot \ 6! } = 630630



Our examples were largely sent or created by pupils and students themselves. Therefore, we would be pleased if you could send us any errors you found, spelling mistakes, or rephasing the example. Thank you!
