$720$ different ways
Work Step by Step
A schedule is an arrangement, an ordered list ...
Order matters, we use permutations.
Permutations Formula:
The number of permutations possible if $r$ items are taken from $n$ items is ${}_{n}P_{r}=\displaystyle \frac{n!}{(n-r)!}$
The number of acts chosen are r=6 from a total of n=6 acts
${}_{6}P_{6}=\displaystyle \frac{6!}{(6-6)!}=\frac{6!}{0!}\qquad $... by definition $0!=1$
$=6\times 5\times 4\times 3\times 2\times 1$
$=720$
