Определение<\/h2>

Очакваната стойност или вероятност на дадено действие, съкратена като EV<\/a>, е средната очаквана печалба или загуба, като се вземат под внимание всички възможни резултати и вероятността те да се случат.<\/p>

 <\/p>

Изчисляване на очакваната стойност\/печалба <\/h2>

За да се изчисли очакваната стойност\/печалба, трябва да се знаят вероятностите и печалбите на всеки възможен резултат въз основа на това, което вече се е случило. EV<\/a> е сумата на всички вероятности за резултат, умножени по съответните печалби.<\/p>

EV<\/a> = Вероятност (Резултат 1) * Печалба 1 + Вероятност (Резултат 2) * Печалба 2 + ... + Вероятност (Резултат n) * Печалба n<\/i><\/p>

Пример:<\/strong><\/p>

Двама играчи хвърлят ези-тура. Ако се падне ези, играч Б плаща долар на играч А. Ако се падне тура, А плаща долар на Б. Вероятността и за двете, ези или тура, е 50%. Оттам и EV<\/a> на двамата играчи е: <\/p>

EV<\/a> = 50% * (+1$) + 50% * (-1$) = 0$<\/i><\/p>

Друг метод за изчисляване на печалбата на залог е:<\/p>

EV(залог) =  Очакван дял от пота- залог<\/i><\/p>

Пример: <\/strong><\/p>

Ирачи А и Б хвърлят ези-тура. Печалбата е както преди, но този път преди всеки рунд и двамата слагат по един долар в пота и накрая победителят получава пота. Всеки играч печели пота от $2 в 50% от случаите. Тeхния очакван дял от пота е значи 50% от $2 или $1. Оттам и EV<\/a> e: <\/p>

EV<\/a> = Equity<\/a> - бет = 1$ - 1$ = 0$<\/i><\/p>

Никой няма нито да спечели, нито да загуби, тъй като губи $1 веднъж и печели $1 следващия път.<\/p>
