c=s
The variable s represents number of additional necklaces and the variable c repres. total # of diamond neck.If louie has 3 neck. in his hand how many are diamond necklaces?
please help me solve
From your data, I cannot tell. However, from your data, it seems that the total number of necklaces = c+s.
However, the probability that all three are diamond necklaces =
c/(c+s) * (c-1)/(c+s-1) * (c-2)/(c+s-2) = ?
