Problem 5: A chain of robot cleaner stores sells three different brands of robot vacuums. Of its robot vacuums sales, 55% are Xiaomi, 35% are iLife, and 10% are Philips. Each manufacturer offers a 1-year warranty on parts and labor. It is known that 9% of Xiaomi robot vacuums require warranty repair work, whereas the corresponding percentages for iLife and Philips are 10% and 8%, respectively. If a customer returns to the store with a robot vacuums that needs warranty repair work, what is the probability that it is a brand Xiaomi?
