My friend has 4 pieces of jewelry – a ring, a necklace, a bracelet and a brooch. Given that she can wear any number of the objects when she goes out, how many combinations of her jewelry does she have to choose from?
If you have not tried to solve it, have a go now. For everyone else, the answer is after the break.
She can wear 4 combinations of 1 piece, 6 of 2, 4 of 3, and 1 of 4 – making 15 different combinations in all. Did you solve it?
