Question 1

How is the probability of a combo bet computed?

Accepted Answer

Legs that are connected — match result and total goals — are priced jointly from the model’s full score matrix, not by multiplying legs one by one. Slips with player or corner legs are priced jointly via 20,000 simulated matches where scorers, assists, cards and corners are sampled together with the result — every correlation carries into the price.

Question 2

What does fair odds mean?

Accepted Answer

Fair odds is 1 divided by the model’s combined probability — the price a bet is worth without the bookmaker’s margin. If you find higher odds than that, the bet holds mathematical value according to the model.

Question 3

Why exactly three suggestions?

Accepted Answer

The suggestions cover three risk levels: a safe one with two legs, a balanced one with three and a bold one with four. Same method — just more that has to come true at once.
