Problem 1 In probability theory, a random variable X is a function from sample space of a random experiment (the set of all possible outcomesi to the real numbers. For instonce, if we were to choose a person ot random, we might let X= height of selected person. We might ask What is the probability that the selected person is between 18 and 19 meters tal? with the symbols P(18
