Suppose 40 % of students who drive to campus carry jump cables in their cars in case of a dead battery emergency. Suppose further your car battery dies and that you do not have jumper cables in your car. Consider the experiment of stopping other students and asking to borrow jumper cables so that you are able to "jump" or re-energize your car battery. Accordingly, let X ="number of students who must be stopped before find a student with jumper cables." i) Give the probability mass function for this random variable, i.e. Px(X = x) ii) Compute the probability Px(X = 1). iii) Compute the probability Px(X < 3) iv) Compute the probability Px(X > 5). v) What is the expected value in this experiment? vi) What is the variance in this experiment?
