Look at each group of 4 to see if one or more of them have hazel eyes:

   7 9 1 8   -  yes

   7 9 1 0   -  yes

   2 5 4 6   -  yes

   1 3 9 0   -  no

   6 0 7 5   -  yes

 

Use the same procedure on the other 15 groups.

When you are done, count the number of times you got "yes".

Divide this number by 20 (the number of groups).
