Solution

Hi, you have not defined how many people are you choosing for the test. Also, correct me If I am wrong.

Total no of people in a group= 12

blue eyes=3

curly hair= 4

and both =1

this does not sum to 12. So, there are people who can have neither of blue eyes or curly hair. Get back to me with no of test sample.
