An initiating event of an accident occurs with a probability p(I) = 0.001. To mitigate this accident, the system is designed with three engineered safety features A, B, and C. The probability of failure of these features installed are P(A) = 0.01; P(B)= 0.005 and P(C) = 0.003. Construct the event tree to describe the system. Also calculate probabilities of failure of each of the different accident events in the event tree.

    hi, my answers seemed strange after using Bayes theorem, so I am unsure if I made the right calculations. Please show your work so I can catch my error :) Extra Credit: ELISA tests are used to screen donated blood for the presence of the AIDS virus. The test actually detects antibodies, substances that the body produces when the virus is present. When antibodies are present, ELISA is positive with probability about 0.997 and negative with probability about 0.003. When...

    A certain system can experience three different types of defects. Let A, (i-1,2,3) denote the event that the system has a defect of type i. Suppose that the following probabilities are true p(A1) = 0.12 p(%) = 0.08 p(A1) = 0.05 p(A1 UA2)-0.14 P(A1 u A3)-0.14 PA2 UAs)-0.11 P(A1 n A2 n A3)-0.01 (a) Given that the system has a type 1 defect, what is the probability that it has a type 2 defect?
