A necklace is made up of 3 beads of one color and 6 beads of another color beads of same color are identical the number of necklace that are possible ?
I have attempted the question in this way :
there are total 9 places and in which 3 objects of one kind and 6 objects of other kind are repeating so number of ways would be $\frac{9!}{3!.6!}$ = 84 which turns out to be a wrong answer when i inspected so please help me where I am wrong.
answer given is 7 possible necklaces
