Della bought a custom charm bracelet with eight charms. If the bracelet has no clasp, in how many ways can she arrange the charms on the bracelet? please show your work.
64? 8 times 8....
well we can rearange 3 things like this a,b,c a,c,b c,a,b c,b,a b,a,c b,c,a this is 6 we had three things so 3! = 3*2 = 6
similarly we can arrange 4 items 4! =24 ways
Yes ... but the bracelet has no clasp
what does that have to do with anything?
It means that a b c c a b b c a are all the same arrangement
ahhh
you can just turn the bracelet, because there is no clasp to define any orientation of it
well looking at my first example of 3 items that would get rid of all but three options
it works out to two a c b c b a b a c is the other
So you can start with the factorial, but then you need to divide by the number of charms to allow for all the positions you can turn the bracelet to
what class is this for? Discreet?
And it goes further than that ... because you could slip the bracelet on either way, I guess
