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.
