"Successive dependent events are a sequence of actions or trials where they occur one after another, in a sequence, and the outcome of the 2nd event is affected ('is dependent on...') the outcome of the 2nd event."
连续相依事件是指一系列按顺序相继发生的行动或试验,其中后一事件的结果受到前一事件结果的影响(即相互依存)。
Drawing a card from a deck of 52 cards looking for an Ace P(Ace) = 4/52, then by NOT replacing whatever card it is changes the probability of getting another Ace in the next draw, to either 3/51 (if the first card was indeed an Ace) or 4/51 (if the first card wasn't an Ace)
从一副52张的牌中抽一张牌,抽到A的概率是4/52。如果抽到的牌不放回,那么下一次再抽到A的概率就会改变——如果第一张牌确实是A,那么概率变为3/51;如果第一张牌不是A,那么概率变为4/51。
Spinning this class's 'wheel of names' looking for Christian P(Christian) = 1/24, then choosing to remove him, means that the probability of landing on Christian again in the next spin is either 1/23, or 0/23, in both cases it's changed..
转动班级的“姓名转盘”,第一次转到克里斯蒂安的概率是1/24。如果选择将他从转盘中移除,那么下一次转动时再转到他的概率要么是1/23,要么是0/23。无论哪种情况,概率都发生了改变。
