Quizplus · Accepted Answer

The number of ordered lists of 4 items chosen from 6 is calculated using permutations since the order matters. The formula for permutations is $P(n, r) = \frac{n!}{(n-r)!}$, where $n$ is the total number of items to choose from, and $r$ is the number of items to choose. Here, $n = 6$ and $r = 4$, so $P(6, 4) = \frac{6!}{(6-4)!} = \frac{6!}{2!} = \frac{720}{2} = 360$.
