In answering a question on a multiple choice test, a student either knows the answer or guesses. Let `3/5` be the probability that he knows the answer and `2/5` be the probability that he guesses. Assuming that a student who guesses at the answer will be correct with probability `1/3` , what is the probability that the student knows the answer given that he answered it correctly

In answering a question on a multiple choice test, a student either knows the answer or gusses. Let 3/4 be the probability that he knows the answer and 1/4 be the probability that he gusses. A ssuming that a student who gusses and the answer will be correct with probability 1/4 What is the probability that the studentthe answer given that he answered it correctly?

Assuming that a student who guesses at the answer with probability 1/4. what is the probability that the student knows the answer given that he answers correctly.?

In answering a question on a multiple choice test for class XII, a student either knows the answer or guesses. Let 3/5 be the probability that he knows the answer and 2/5 be the probability that he guesses. Assume that a student who guesses at the answer will be correct with probability 1/3. Let E_1, E_2 , E be the events that the student knows the answer, guesses the answer and answers correctly respectively. Based on the above information, answer the following What is the probability that the student knows the answer given that he answered it correctly?
