In fact, with odds of 1.9, the probability of winning is not 50% in sports betting, but 52.63%. This is the exact probability of winning with this odds. The probability of winning is calculated using the formula 100/odds. That is, if we divide 100 by 1.9, we get the figure 52.6315…%
At first glance, it may seem that this figure is close to the probability of 50%. But the difference is 2%. This is a fairly large difference in probabilities, which can be summed up in your strategy or subtracted from it in the long term, which can lead to very large wins or losses over the long term.
This difference must be taken into account in any case.
I don't think it's accurate.
You can try to calculate with the moneyline odds, there's a match I calculate both of the teams, when I sum both of the winning percentage, it doesn't reach 100% and sometime it bigger than 100%.
It should be odds 1/(odds 1+odds 2) or vice versa.
I think people shouldn't bet based on probability like team one has 52% win chance, another one is 48%, both of them are pretty much same, but their history, popularity and recent performance are different, so bettors can use this analysis to make a bet.
