96 ways

Step-by-step explanation:

Let's call flags of countries from Africa as A₁, A₂, A₃, A₄, and from Europe as E₁, E₂, E₃ and E₄

We have to display the flags always beginning with one flag from Africa let's take A₁

For that flag, we have 4! possibilities Then 4! is:

4*3*2*1 = 24

As we have 4 different Flags from Africa, we will have

4*24 = 96 possibilities
