A chain of video stores sells three different brands of DVD players. Of its DVD sales, 50% are brand A (least expensive), 30% are brand B, and 20% are brand C. Each manufacturer offers a one-year warranty on parts and labor. It is known that 25% of brand A DVD players require repair work under warranty, whereas brand B DVD players require 20% warranty repair work and brand C DVD players only require 10% warranty repair work . Suppose we randomly select a single purchased DVD player out of all players purchased, what is the probability that it is both a Brand A player and required repair work under warranty.
