Quizplus · Accepted Answer

$P(8,5)$ refers to the number of permutations of 8 items taken 5 at a time. The formula for permutations is $P(n, k) = \frac{n!}{(n-k)!}$. Plugging in the values, we get $P(8,5) = \frac{8!}{(8-5)!} = \frac{8!}{3!} = \frac{8 \times 7 \times 6 \times 5 \times 4}{3 \times 2 \times 1} = 6720$.
