1. Compute the reliability of a two-element standby system with equal online and a nonzero standby failure rate. Include coverage.

2. Consider the effect of common mode failures on the computation of Eq. (3.45). How large would the probability of common mode failures have to be to negate the advantage of a 20 : 21 system?
