Q1. Twelve differently coloured beads are arranged around a necklace. How many different arrangements are possible?
ALSO
Q2. Nine beads are arranged on a bracelet. How many different ways are possible?
1. Do I assume the necklace is circular? So the possible amount of arrangements would be 11! But the textbooks answer is completely different. Please help?
2. As above.
