As an added incentive for students to do homework for their probability course, the professor randomly picks two students at each class meeting. These two students are asked to explain a homework problem. On a particular day, five students from the class of 20 students have not done the homework. Let the random variable X be the number of students picked who have not done the homework. What is the probability mass function of X?
A tour guide is in charge of overseeing groups of 3 visitors during the trip. There is a probability of 2/3 that a visitor in the group will ask the tour guide a question. The tour guide has been asked by the bus driver to make a hypothesis about the number of questions the next group will ask. 1. Write the table and formula (if any) of the probability mass function for the number of questions asked by the group of 3.2. How many questions should the tour guide expect, and what is the standard deviation?
