5. The thickness, x, of a protective coating applied to glass shower doors designed to ensure the longevity and clarity of the glass follows a uniform distribution over the interval from 10 to 40 microns. Find the probability that the coating is less than 20 microns thick. a. a. 0.3333 b. 0.6667 6. Which of the following situations describes a binomial random variable? You play two games against the same opponent. The probability that you win the first game is 0.4. If you win the first game, the probability you also win the second game is 0.2. You are interested in the probability that you will win both games? b. A school newspaper reporter decides to randomly survey 12 students to see if they will attend Tet (Vietnamese New Year) festivities this year. Based on past years, she knows that 18% of students attend Tet festivities. You are interested in the number of students who will attend the festivities.
