Law of total probability practice problems
WebSo, the probability that the student doesn't know the answer AND answers correctly is. 1∕3 ∙ 1∕4 = 1∕12. Thereby, the student answers correctly. 2∕3 + 1∕12 = 3∕4 of the time. Now, for the conditional probability we want to view that 3∕4 as if it was 1 whole, which we achieve by multiplying by its reciprocal, namely 4∕3. Web6 jun. 2024 · The law of total probability is also referred to as total probability theorem or law of alternatives. Note – The law of total probability is used when you don’t know the probability of an event, but you know its occurrence under several disjoint scenarios and the probability of each scenario.
