Question *A printer manufacturer obtained the following probabilities from a database of testresults. Printer failures are associated with three types of problems: hardware,software, and other (such as connectors), with probabilities 0.1, 0.6, and 0.3,respectively. The probability of a printer failure given a hardware problem is 0.9, given asoftware problem is 0.2, and given any other type of problem is 0.7. If a customer entersthe manufacturer's Web site to diagnose a printer failure, what is the most likely causeof the problem?None of theseSoftware categoryOther categoryHardware category

R4.1. Quality control A consumer organization estimates that 29% of new cars have a cosmetic defect, such as a scratch or a dent, when they are delivered to car dealers. This same organization believes that 7% have a functional defect- something that does not work properly-and that 2% of new cars have both kinds of problems. a) If you buy a new car, what's the probability that it has some kind of defect? b) What's the probability it has a cosmetic defect but no functional defect? c) If you notice a dent on a new car, what's the probability it has a functional defect? d) Are the two kinds of defects disjoint events? Explain. e) Do you think the two kinds of defects are independent events? Explain.
67.9% of all patients admitted to the intensive care unit (ICU) have a fever, 35.6% have some sort of infection, and 17.2 % have both problems. find the probability that a randomly chosen patient in this ICU had with a fever , given that they have an infection
6. A large group of people is to be checked for two common symptoms of a certain disease. It is thought that 20% of the people possess symptom A alone, 30% possess symptom B alone, 10% possess both symptoms, and the remainder have neither symptoms. For one person chosen at random from this group, find these probabilities (a) The person has neither symptom. (b) The person has at least one symptom. (c) The person has both symptoms, given that the person has symptom B.
A company buys microchips from three suppliers I, II and III. Supplier I has a record of providing microchips that contain 10% defective; supplier a defective rate of 5% and supplier III has a defective rate of 3%. Suppose 10%, 40% and 50% of the current supply came from suppliers I, II and III, respectively. If a randomly selected microchip is defective, what is the probability that it came from supplier II? Express your answer accurate to two decimal places. O 48 O..40 O something else O 44 O 41
A major traffic problem in the Greater Cincinnati area involves traffic attempting to cross the Ohio River from Cincinnati to Kentucky using Interstate 75. Let us assume that the probability of no traffic delay in one period, given no traffic delay in the preceding period, is 0.95 and that the probability of finding a traffic delay in one period, given a delay in the preceding period, is 0.75. Traffic is classified as having either a delay or a no-delay state, and the period considered is 30 minutes. (a) Assume that you are a motorist entering the traffic system and receive a radio report of a traffic delay. What is the probability that for the next 60 minutes (two time periods) the system will be in the delay state? Note that this result is the probability of being in the delay state for two consecutive periods. = (b) What is the probability that in the long run the traffic will not be in the delay state? (Enter your probabilities as fractions.) No Traffic Delay Traffic Delay π 1 =…
