1. Assume that a system consists of five series elements. Each of the elements has the same reliability p, and the system goal is R_s
= 0.9. Find p.

2. Assume that a system consists of five series elements. Three of the elements have the same reliability p, and two have known reliabilities of 0.95 and 0.97. The system goal is R_s
=0.9. Find p.
