    This content was COPIED from BrainMass.com - View the original, and get the already-completed solution here!

    In answering a question on a multiple choice test, a student either knows the answer or he guesses. Let p be the probability that he knows the answer and 1-p the probability that he guesses. Assume that a student who guesses at the answer will be correct with probability 1/m, where m is the number of multiple choice alternatives.

    What is the conditional probability that a student knew the answer to a question given that he answered it correctly?
