- True or False? In counting combinations, order matters. In counting permutations, order matters. For a set of n distinct object, the number of different combinations of these object is more than the number of different permutations. If we have a set with five distinct objects, then the number of different ways of choosing two members of this set is the same as the number of ways of choosing three members.arrow_forwardAn Internet service provider requires its customer to select a password consisting of four letters followed by three digits. Find how many such passwords are possible in each of the following cases: a Repetition of letters and digits is allowed. b Repetition of letters and digits is not allowed.arrow_forward
