+342 is a longshot. The bookmaker prices the outcome at 22.62%, and the payout of 342.00 per 100 staked is the compensation for how rarely it lands. Longshots carry more margin than any other part of the market, which is why devigging methods disagree most at prices like this one.
The vig at +342
If both sides of a two-way market were priced at +342, the implied probabilities would add up to -54.75% above 100%.

Use the devig calculator to do the same for any market.
