Definice<\/h2>

Očekávaná hodnota vaší akce nebo také očekávání, zkráceně EV<\/a>, je průměrný zisk nebo ztráta, které jsou výsledkem situace, při které vezmete v potaz všechny možné výsledky a jejich pravděpodobnosti.<\/p>

 <\/p>

Výpočet Expectation<\/h2>

Abyste mohli spočítat toto očekávání, musíte znát pravděpodobnosti a možné přínosy ze všech možných výsledků, z toho co již vyšlo najevo. EV<\/a> je součtem všech možných výsledků, které vznikají porovnáním přínosu výsledku a pravděpodobnost, že to bude právě tento výsledek.<\/p>

<\/p>

EV<\/a> = P(outcome 1) * Payoff 1 + P(Outcome 2) * Payoff 2 + ... + P(Outcome n) * Payoff n<\/i><\/p>

Příklad:<\/b><\/p>

Dva hráči hází mincí. Když padne panna, hráč B zaplatí hráči A dollar. Když orel, hráč A platí dolar hráči B. Pravděpodobnost toho že padne orel nebo panna je shodně 50%. Proto EV<\/a> pro oba hráče je:<\/p>

<\/p>

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

Jiná metoda výpočtu ziskovosti sázky je:<\/p>

EV(Bet<\/a>) = Pot<\/a> Equity<\/a> - bet<\/a><\/i><\/p>

Příklad: <\/b><\/p>

V tomto příkladu hráči A a B opět hází mincí. Systém je stejný jako v předchozím příkladu s tím rozdílem, že před hozením mincí oba hráči dají dolar do společného banku, který nakonci připadne tomu, kdo vyhraje hod mincí. Každý tedy může vyhrát bank 2$ s 50% šancí při každém hodu. Jejich pot<\/a> equity<\/a> je proto 50% z 2$ nebo 1$. Proto je EV: s<\/p>

EV<\/a> = Equity<\/a> - Bet<\/a> = 1$ - 1$ = 0$<\/i>
Ani jeden z hráčů nic nevyhraje ani neprohraje, dokud ztrácí 1$ v polovině případů a vyhrává ho v té druhé polovině případů. <\/p>
