If big brown goes off at 1-2, what is the payoff for a $100 bet if he wins?

Question

would it be $50 profit?

Answer 1

Yes.  You will win $50 plus get your $100 bet returned.  1 to 2 odds means you get one dollar for every two you bet.  2 to 1 odds would return $6 on a $2 bet - 2 x $2 plus your $2.

Answer 2

You'd be lucky to get him at 1-2. Realistically the payout would end up more around 120 dollars. Of course, that's an almost guaranteed 20 dollars, but it's not COMPLETELY guaranteed.
