Webb7 dec. 2024 · If the outcome of one event does not affect the outcome of the other event, the events are independent. An example of dependent events is the probability of the clouds in the sky and the probability of rain on that day. The probability of clouds in the sky has an impact on the probability of rain that day. They are, therefore, dependent events. imagine bookshopWebbTwo events A and B are independent if the knowledge that one occurred does not affect the chance the other occurs.

WebbNon-independent events. The gambler's fallacy does not apply when the probability of different events is not independent. In such cases, the probability of future events can change based on the outcome of past events, such as the statistical permutation of events.
