Chance assessment & theoretical repayment rate
When a bookmaker places odds on a match, this is based on an assessment of the probability of the individual outcome of the match; i.e. a chance assessment.
In addition, the bookmaker has set an expected earnings margin on the match, which is expressed in a theoretical repayment percentage, which corresponds to what percentage of players' deposits they theoretically expect to pay back in winnings.
