¿Cómo calculan las casas de apuestas las cuotas?

Hello @Jaisingh!

Thank you for your interest in this subject.

Basically, bookmakers start by figuring out how likely each possible outcome is, then adjust those odds a bit to make sure they have a margin for themselves. For instance, if a bookmaker thinks a team has a 50% chance of winning, the "fair" decimal odds would be around 2.00. But to cover their bases, they might offer odds like 1.90 instead.

They consider tons of factors when estimating those probabilities, like past performance, player injuries, home-field advantage, and all sorts of stats. Once the odds are published, though, they don't stay fixed. Bookmakers keep adjusting them based on how people are betting.

If a lot of money comes in on one side, they'll shorten those odds and lengthen the others to balance their exposure. And for live betting, they even tweak the odds on the fly based on what’s happening in the game.

You might hear the term "overround" or "vig," which is just their way of saying they add a little extra to ensure they always have a margin. That means the combined probabilities of all outcomes usually add up to more than 100%. 

Just keep in mind that odds are estimates - they reflect what the bookmaker thinks, and they can change as new info comes in or betting trends shift. It's all part of the fun!

Hope this clears things up for you!

Best regards,

Calculan las cuotas combinando análisis estadístico, modelos matemáticos y la aplicación de un margen de ganancia conocido como vig u overround, para asegurarse de obtener beneficios sin importar el resultado.

•Análisis de probabilidad real: Los estadísticos y algoritmos de la casa evalúan datos como lesiones, estadísticas históricas, localía, rendimiento reciente y alineaciones para estimar la probabilidad real de que ocurra un evento.

Ejemplo: 50% de probabilidad de ganar.

•Conversión a cuota justa: A partir de la probabilidad, se calcula la cuota teóricamente justa dividiendo 100 entre el porcentaje de probabilidad.

Ejemplo: una probabilidad del 50% equivale a una cuota justa de 100 / 50 = 2.00.

•Aplicación del margen de ganancia (Overround): La casa de apuestas ajusta las cuotas a la baja para que la suma de las probabilidades implícitas de todos los resultados posibles supere el 100% .

Ejemplo: 105% en total.

Ese exceso del 5% es el beneficio garantizado para la casa.
