Answer:

6188 different combinations of people

Step-by-step explanation:

This is a combination problem since it does not matter the order of people that answer the phones.  The combination looks like this:

₁₇C₅ = [tex]\frac{17!}{5!(17-5)!}[/tex]

This expands to

[tex]\frac{17*16*15*14*13*12!}{5*4*3*2*1(12!)}[/tex]

The 12! cancels out in the top and bottom so the remaining multiplication leaves you with

₁₇C₅ = [tex]\frac{742560}{120}[/tex]

which divides to 6188
