nitraiddQ 2021-09-10A possible recall of chart-topping car in the world is now a major concern of its manufacturer. The issues of this car are from defects on its systems. 0.40 failure is probable from the brake
system, a probability of 0.20 from power-transmission failure, 2 0.10 probability from fuel system malfunctioning, and a defect of 0.40 in some parts of the car. What is the probability that
there are no defects in either the brakes or the power-transmission system if these two systems fail with 2 probability of 0.10 simultaneously?
