Answer:
491,400 different slates of candidates are possible
Step-by-step explanation:
The order is important.
For example, a slate of John, Rose, Laura and Elisa is different than a slate of Rose, John, Laura and Elisa, since the roles of John are Rose are exchanged.
Permutations formula:
The number of permutations of x elements from a set of n elements is given by:
[tex]P_{n,x} = \frac{n!}{(n-x)!}[/tex]
In this problem, we have that:
4 roles to be chosen from a set of 28 members. So
[tex]P_{28,4} = \frac{28!}{(28-4)!} = 491400[/tex]
491,400 different slates of candidates are possible
