Man United win: evens (one/1 or 2:0)

Attract: 2/1 (three:0)

Portsmouth Gain: five/1 (6:0)

We’ll now change these real odds into genuine percentages:

Gentleman United to get proportion probability: Evens (or one-1) = (50%)

The attract percentage likelihood: two-one = (33%)

Portsmouth to acquire percentage likelihood: five-1 = (16%)

If we insert all these percentages up we get a hundred% which is termed a complete ‘book’ and this would go away the bookmaker essentially breaking even it doesn’t matter what the outcome of your match.
