how many possible combinations can there be with the numbers 6,6,4,4,1?

Question

anonymous · Answer

if they were all different you would have 6! combinations, but since you cannot tell the 6s apart, nor the twos, it is 
$$\frac{6!}{2\times2}$$

what is an additional number between friends?  ok i was wrong, maybe try 
$$\frac{5!}{2\times 2}$$ if you want to actaully  get the correct answer

anonymous · Answer

anonymous · Answer

$$\frac{5\times 4\times 3\times 2}{2\times 2}=5\times 3\times 2=30$$
(did i get that right?)

anonymous · Answer

looks correct, but what is the general formula?

anonymous · Answer

$$\frac{5!}{3!}$$ for the second one

anonymous · Answer

so that otheer one is really 2!x2! in the denominator?

anonymous · Answer

yes, if you want to think of it that way. the number of ways you can permute 2 things is 2! = 2
