Please explain more about Winning and Drawing in Question 4

Even numbers (2, 4, 6, ...) and prime numbers (1, 2, 3, ...) are not mutually exclusive. 

Heads and Tails, I believe its sample space contains only Heads and Tails. That is why they are mutually exclusive and be complement for each other. 

Black cards and Red cards, I didn't know if its sample space has any other color. They are of course multually exclusive. May be I overthink about other possible color lol.

but not really understand the sample speak of winning and drawing (I'm not native English). 

Sample space* (typo)

In the sample space there's

- Winning

- Drawing

- Losing

So just winning and drawing do not account for all possible cases.

Thanks Klim
