Cricket betting sites assess the probability of a particular outcome (in the match) happening and accordingly adjust the odds after factoring in their ‘margin’ or ‘juice’. This is how all the betting markets are set. If you convert the odds into percentages, you will see they never equal 100%; there will always be percentage points remaining. That’s because that is the bookmaker’s ‘house edge’ or ‘vigorish’ – that is, the profit guaranteed for a betting site, given that all bets are proportionate to the prices.
