Resolved: 4th question: even and prime number
I think that even and prime numbers are not a complement, hence it is a correct solution to question number 4.
I think it should be changed to even and odd numbers. this way only selection number 2 (winning and drawing) will be the correct answer.
The question first requires the two sets are mutually exclusive. Even and primes numbers are not mutually exclusive, so this option is not a correct answer.
Hope this helps.
