I would like to know how to solve the following question:

A student answers a question in American test that has m options that are given as follows:
In probability P the student has learned the question and therefore knows how to choose the correct answer, otherwise he guesses the question.
a) What is the probability that the student studied the subject of the question given that he answered correct on the question?
b) Analyze the result for m=1 and m->inf

Hi lola9991,

How would you explain or write Bayes' Theorem to start? How would you write A in conditional probability notation?
