A system (circuit) has two parallel branches upper and lower. The upper branch consists of two components 8 and s2 in series. The lower branch consists of only $3. Suppose that the components fail independently and the probability of failure of the component si is pi. Find the probability of the event that the system is working. A system (circuit) has two main components that are in series left and right. The left component consists of only $. The right component consists of two parallel components 82 and 83. Suppose that the components fail independently and the probability of failure of the component si is Pi. Find the probability of the event that the system is not working.
