How many ways can five Monopoly pieces be arranged in a row?

(a) This is just '8' people being arranged in a row: '8! = 40,320' (b) Regard the '2' boys as one "unit" and so there are '7' "units" to arrange. This can be done '7! = 5040' ways. The boys can be arranged in '2! = 2' ways, so the required answer is '7! * 2! = 10,080' (c) There are only '2' possibilities: the boys are together or they are not.
