Question 1 0.70 B 0.90 0.95 A D 0.80 C An electrical system consist of four components with the probability of working of each component is shown in figure. The system works if components A and D work and either of the components B and C works. Assume that the four components work independently. Find the probability that i. the entire system works. (3 marks) ii. the component C does not work, given that the entire system works. (2 marks)
