I need help with these two questions:
How many permutations are there of the word collect if the 2 l's have to be together and the two c's have to be separated?
I got as far as 360 because if u keep the l's together you would get 6! x 2!
2! x 2!
but after that I am stuck on what to do next
and the other question:
How many ways can 4 couples be seated at a circular table so that the couples are never sitting together?
i knoe 8! / 8 gives the possibilities of all of them at one table, but since some of them can sit together i don't know what to do
can someone help me finish of these questions?
