Answer:

95,040 different cast are possible

Step-by-step explanation:

In this case the order in which the actors are selected for the 5 different roles is important. Therefore we use the permutations formula.

nPr =\frac{n!}{(n-r)!}

Where n is the number of items you can choose and choose r from them.

In this case n = 12 and r = 5

12P5 =\frac{12!}{(12-5)!}

12P5 =\frac{12!}{7!}

12P5 =95040
