A complex electronic device contains three components, A, B, and C. The probabilities of failure for each component in any one year are: 0.01, 0.03, 0.04, respectively. If any one component fails, the device will fail. If the components fail independently of one another, what is the probability that the device will not fail in one year?

A random sample of n = 300 measurements is drawn from a binomial population with probability of success .43. Give the mean and the standard deviation of the sampling distribution of the sample proportion, .

Table 1: Thermal vs. Voltage Failure Results (all 500 components) Voltage Failure No Voltage Failure Total Thermal Failure 50 85 135 No Thermal Failure 65 300 365 Total 115 385 500 Additionally the engineer reports: 70 components experienced a mechanical failure 40 of the components with mechanical failure also had a thermal failure 40 of the components with mechanical failure also had a voltage failure 10 components experienced all three failure types simultaneously Let A = thermal failure, B = voltage failure, C = mechanical failure Given that a component experienced at least one failure, what is the probability it experienced exactly one failure type?
