Are odd and even equally likely?
The math is too hard for me, but a similar, very simplified version yields this result: number 1, 2, 3, 4. Pick 2 numbers.
Possibilites:
1,2 odd
1,3 even
1,4 odd
2,3 odd
2,4 even
3,4 odd
That's one more odd than even. Don;t know if this correlates to a pick 20 on a field of 80, but I'm picking odd on that basis anyway.
