WebbA set of events are called exhaustive, if at least one of them occurs definitely whenever the experiment is performed. It means the probability of any one of them to happen is 100%. In this kind of an event, all events come together to take up the entire sample space. Example of an exhaustive event, Suppose you appear for an exam. WebbA and B are events that are subsets of the sample space.

The probability of the second event is 4/19. And the probability of the third event is 11/18. The probability is 5/20 x 4/19 x 11/18 = 44/1368 = 0.032. You could also express this as 3.2%.

WebbIn probability theory and statistics, the Poisson distribution is a discrete probability distribution that expresses the probability of a given number of events occurring in a fixed interval of time or space if these events occur with a known constant mean rate and independently of the time since the last event. It is named after French mathematician … WebbIn probability, we say two events are independent if knowing one event occurred doesn't change the probability of the other event. For example, the probability that a fair coin shows "heads" after being flipped is 1 / 2 1/2 1 / 2 1, slash, 2 .

WebbThe gambler's fallacy, also known as the Monte Carlo fallacy or the fallacy of the maturity of chances, is the incorrect belief that, if a particular event occurs more frequently than normal during the past, it is less likely to happen in the future (or vice versa), when it has otherwise been established that the probability of such events does not depend on what … WebbExample 6: The odds against a certain event is 5 : 2 and the odds in favour of another event is 6 : 5. If both the events are independent, then the probability that at least one of the events will happen is Solution: Let A and B be two given events. The odds against A are 5:2, therefore P (A) = 2 / 7 .
