Can you please explain how to correctly solve this problem. Starting from top to bottom.

0.97 0.96 0.88 0.97 0.96 0.88 This production process has two main types of subprocessesone on top with three components in series and then the bottom with the same set-up. First we should determine the reliability of the top subprocess with three components in series: 0.97 0.96 0.88 The average reliability of a system with n components in series is given by: Rs =R, R2 R3 X... Rn. The reliability of this = 81.95 % (enter your response as a percentage rounded to two decimal places). Once you have the reliability of the lower and upper subprocesses, determine the reliability of the overall system by considering them in parallel. For two components in parallel with reliabilities R7 and R2, the effective system reliability is = 1 -[(1 -R1)*(1 - R2)]. The reliability of the whole system shown at the top = 96.74% (enter your response as a percentage rounded to two decimal places). As compared to a system without backup (shown below), 0.97 0.96 0.88 the reliability of the system with backup is higher by 96.74% 81.95% = % (enter your response as a percentage rounded to two decimal places)
