凱利公式喺高級賭徒的世界大名鼎鼎,咁到底咩係凱利公式呢?
先問你一個問題,如果你眼前有一個簡單 1 賠 1 嘅公平賭局, 而你可以重覆參與幾多次都得 ,你有$100,你會點賭?⚖️
如果你係冒險主義, 每一次都100%全押注All-in所有金錢,雖然贏嘅話次次都立即翻倍💰;但一輸就會立即變零,一無所有💸
如果你係保守主義,謹慎地每次下注$1,贏就賺$1 ,輸就蝕$1, 小朋友玩泥沙,咁嘥時間不如正正經經打份工好過😫
全押注太多,賺$1又太少,咁應該投入幾高比例呢? 作為高級賭徒,你一定要識凱利公式(Kelly Formula)📌
——————————————
🧮 凱利公式係一條可應用喺多次隨機賭博遊戲嘅公式,令到資金的期望值最高
🌟 f* =(bp-q)/ b 🌟
f* = 應投注的資本比值
p = 獲勝的概率(也就是拋硬幣正面的概率)
q = 失敗的概率,即 1 – p(也就是硬幣反面的概率)
b = 純利率(也就是一賠1的1)
公式上面的分子 bp-q 代表「贏面」
———————————————
例子:一局遊戲,贏的概率 p、輸的概率q 都為 0.5
贏就一賠1,所以純利率=1
👉(bp – q) / b = (1 * 0.5 – 0.5) / 1
👉= 0%
❗拿出資金的 0% 進行下注,已經能夠使賭局收益最大化。
⚖️ 即係話,原來就算賭局係公平嘅,根據數學都唔值得押注任何金錢。更何況,世界上大部分賭局都對玩家唔 fair 嘅,可想而之,連 fair 都唔值得賭,更何況係唔 fair 嘅呢? 大家有睇過賭 Sir 嘅 Youtube Channel 就知道喇,所以大家切勿沉迷賭博啊❗
