Question

You have seven balls labelled 1,2,…,7 and seven unlabelled, indistinguishable boxes. How many different ways can the balls be placed into the boxes?

Details and assumptions
Since the boxes are indistinguishable, putting all 7 balls into one box is the same as putting all 7 balls into a different box.
