The probability is a number between 0 and 1; the larger the probability, the more likely the desired outcome is to occur. For example, tossing a coin twice will yield "head-head", "head-tail", "tail …

在數學上，事件發生的機會可用一個數來表示，稱該數為 概率 （Probability）。 我們日常所見所聞的事件大致可分為兩種：

Probability tells us how often some event will happen after many repeated trials. You've experienced probability when you've flipped a coin, rolled some dice, or looked at a weather …

Probability（英语单词，音标英 [ˌprɒbəˈbɪləti]/美 [ˌprɑːbəˈbɪləti]）指事件发生的可能性，在数学中特指用0到1区间数值量化随机事件发生几率的概率概念，复数形式为probabilities。

Probability is all about how likely is an event to happen. For a random experiment with sample space S, the probability of happening of an event A is calculated by the probability formula n …
