Question: In Exercise 3 101 on page 108 the price of a
In Exercise 3.101 on page 108, the price of a certain commodity (in dollars) and its total sales (in 10,000 units) were denoted by P and S. Use the joint density given in that exercise and the distribution function technique to find the probability density of V = SP, the total amount of money (in $ 10,000 units) that is spent on this commodity.
Answer to relevant QuestionsWith reference to Exercise 3.93 on page 107, find the probability density of the average mileage of two such tires. Assume independence. According to the Maxwell-Boltzmann law of theoretical physics, the probability density of V, the velocity of a gas molecule, is Where β depends on its mass and the absolute temperature and k is an appropriate constant.
