Parlay math in American odds
A sportsbook prices two independent events at American odds of each (risk \110$100$). A parlay pays only if both legs win.
Convert to decimal, find the fair and offered parlay prices, and compare the effective margin to a single bet.
Show a hint
Convert to a decimal price first, then treat the parlay exactly like the multiply-the-odds problem.
