vacuum cleaner company has three machines, each making electric cords.
Machine 1 is the oldest and of all units it produces 1.2% do not meet quality standard (of not being damaged after an abrupt change of voltage). Machine 2 produces 0.8% of bad units, while the newest, machine 3, makes 0.5% of units with unacceptable quality. Of all the cords produced, 20% are made on machine 1, 35% are made on machine 2 and the rest on the machine 3. The cord is used as a part of vacuum cleaner that the company makes. If a customer randomly buys a vacuum cleaner produced by this company, what is the probability that the cord does
not meet the quality standard?
