21 point teaser EV question
This is kind of a probability question but it relates to NFL betting so I'll post it here:
My friend is thinking of doing a 10 team, 21 point teaser for the NFL. He has to risk $170 to win $100. He has to go 10/10 to win, but he gets 21 points for each game. What is the EV for this and how would one calculate it? |

Re: 21 point teaser EV question
Using data from NFL games from 93 to 04, I get 94.837% of the games that a team managed to cover the spread +21 points. I'm not sure how ties effect this bet, but I will ignore them for now.
Anyway, the probability of winning this is simply .94837^10 or about 58.85%. That's not enough to make it profitable (needs ~63%) but it's not impossible that if your friend picks the correct 10 sides that it could be +EV. Frankly I'm a little surprised because when I read this I thought it would be a much bigger "suckers" bet. Edit: What are the rules on ties? This could have a pretty significant effect, and if "ties lose" is the case, the win pct drops to 55.3%. |

Re: 21 point teaser EV question
My guess is that ties lose. The OP said you had to win them all. Of course, they could just mean that you can't lose even one.

Re: 21 point teaser EV question
All their other teasers use the "ties count as no action and the teaser reverts to a one-fewer-selection bet" - it's not likely they'd have one rule for 6 point teasers and a different one for 20 pointers.

All the way at the bottom it says "ALL TIES LOSE" |

I'm filing this under "oops". - Chris |

Re: 21 point teaser EV question
Can you include totals too, or just sides?

Re: 21 point teaser EV question
5Dimes takes these things. They call them Monster Teasers and ties lose.
Tech...you can use totals in them too,even team totals. I was looking at them the week Baltimore played Pittsburgh and the over for the Ravens for a 14 pt teaser was 4 [img]/images/graemlins/smile.gif[/img] |
