Are you asking in terms of understanding what that means? That means it’s literally a coin flip in the betting odds. But instead of +100/+100 the betting site has to take their cut. So what it means is that if you place a bet of $110 and win you get $100 back. So if they get an even amount of money on both fighters, as they expect to, they give $100 of each of the losing bettors money to the winning bettor and take the extra $10 for themselves (adjust by percentage for any other amount bet 110 is just the simple math)how are Jamahal and Khalil both -110?
