Probability Question

Hi all,

Can't seem to get my head around this, so resorting to this forum.

Problem:
If I have 2 or 4 or 6/ 8/ 10/ 12 players play in a game, who can make 10 bets each (with 50/50) success rates.

10 points for Correct bet, -5 points for Incorrect bet

And each player makes all 10 bets...

How often is it likely that 2 players tie in 1st place if there were, as mentioned above, 2 or 4 or 6/ 8/ 10/ 12 players play in a game.

Can one please give workings with brief explanations? (If you find it easier to explain using excel sheet, that will work great!)

Hoping a maths guru to solve the problem fast!!

Thanks a ton,
Dex

For two players, there is a tie when they have the same number of winning bets.
What is the probability they each have no winning bets?
What is the probability they each have one winning bet?
