Q. Arianna, Xavier, and Rebecca have been invited to a dinner party. If they each drive there separately, in how many different orders can they arrive?

List of people: List of people: Arianna, Xavier, and Rebecca. $\newline$ We need to determine the number of different orders in which they can arrive at the dinner party. $\newline$ Since there are $3$ people, the number of orders will be $3!$ ( $3$ factorial).
Calculate factorial: Calculate the value of $3!$ .
Number of orders = $3!$
= $3 \times 2 \times 1$
= $6$
