If you’ll allow another sports betting post. Some of you math nerds love this stuff though . Promo offers a “risk free” 1st score basketball bet. You bet $25 and receive it back in free bets if it loses. Most of these odds start at +400 or +500 for the favorite and step up from there. I work through 5 accounts. So, question is how can I figure the odds that one of the 5 favorites is the one who makes the 1st basket? For simplicity sake, let’s assume it’s +500, +600, +700, etc. Thanks
