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.

Number of Ways = ₄P₄ = 24

Step-by-step explanation:

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.

i.e

Number of Ways = ₄P₄ = 24

i think it would be 42cm
