A machine consists of two components: A and B. The machine needs both components to operate. As soon as one component breaks the machine fails. The time until component A breaks is an exponential with rate AA = 0.4 per year. The time until component B breaks is an exponential with rate AB = 0.4 per year. The two components are independent. Compute the probability the machine remains functional for at least another 3 years.
On average, 7% of the motors produced by a machine are faulty. A random selection of 10 motors are selected from a large batch so that the probability remains constant. Determine the probability that AT LEAST one motor is faulty. Give your answers correct to 3 decimal places.
A class contains 50 students. The probability of failing in one of the courses for each student is 0.035, but there is no chance to fail in more than one course. You know that a student failed in a course, the probability that the fail reason in non-attendance is 0.025. All other fail reasons are low average. The examinations are private, so the results are mutually independent. Let X and Y be the numbers of failed students due to non-attendance and due to low average, respectively, in that class this semester. Find the joint MGF
Patients at a hospital appear to arrive independently from each other, at a constant rate of approximately 2.1/hr. The working week of this hospital is 7 days, each comprised of four 3-hour shifts. 1. A shift is considered “light” if at most two patients arrive during it. What is the probability that a shift is light? Calculate the probability that in a day, there are exactly two light shifts.
