Question

A six-sided number cube is rolled twice. Which expression can be used to find P(5, then3)?

Answer 1

I believe it is asking you to find \(\text{nPr(5,3)}\)
Just use the formula for permutations
\[\text{nPr(5,3)}=\frac{5!}{(5-3)!}\]
\[=\frac{5 \times 4 \times 3 \times \cancel{2!}}{\cancel{2!}}\]
\[=5 \times 4 \times 3\]
You can evaluate that
