Betting odds are calculated by the probability of

something happening. For example, if the odds are 4-1 this suggests there ❤️ is a 1 in 5

chance of winning (4+1), or calculated as 1 / (4+1) = 0.2 which means there ❤️ is a 20%

chance of the outcome happening. The winnings you would receive from a bet is

calculated by multiplying ❤️ your stake by the odds. So a stake of £1 would pay £4 profit,
