In a statistics class there are 40 students. Each time, the teacher chooses randomly one student to answer one question and then the teacher not return the chosen name. There are a total of three questions. Marja defines the events:‖
* A = She is called upon to answer the first question,‖ she says.
* B = She is called to answer one of three questions. Then what is the probability that she is called to answer the first question, given that she is chosen to answer one of the three?
