The British Queen is to receive 4 foreign dignitaries. The digni- taries are sensitive to the order in which they are received.
In how many ways can the Queen receive them? Give your answer in terms of per- mutations or combinations and explain your choice. You do not have to evaluate.
Given that there are going to be 4 dignitaries, and that they are sensitive to the order (i.e the order of the dignitaries matter), hence the total number of ways they can be arranged can be found by permutating 4 dignitaries.
