Question 4. A power electric circuit has safety fuse. Three types of faults A,B and C may appears in the system with probabilities 0.1, 0.2, and 0.3. In case of fault A, fuse acts and disconnects power with probability 0.9, in case of fault B it acts with probability 0.8 and in case of fault C it acts with probability 0.85. A. What is the probability that fuse acts and disconnects the power. B. Let assume that fuse acted, what is the probability that fault A have been occurred?
