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?
