Before the distribution of STAAD, every 4th Blu-ray disk (BD) is tested for accuracy. The testing process consists of running 4 independent programs and checking the results. The failure rates for the 4 testing programs are, respectively, 0.01, 0.03, 0.02, and 0.01. A.)What is the probability that a BD was tested and failed any test? B.)Given that a BD was tested, what is the probability that it failed program #2 or #3? C.)In a sample of 100, how many BDs would you expect to be rejected? D.)Given that a BD was defective, what is the probability it was tested?
