Consider two components with the following characteristics. 

Component C₁: modeled using a Weibull failure distribution with parameters 2.2 and 900 days 

Component C₂: modeled using an exponential failure distribution with mean time to failure of 800 days 

Compute and compare the reliability values in the following two systems at 1300 days: 

(a) A system with two components C₁ and C₂ arranged in a parallel configuration. 

(b) A system with one such component (Component C₂) with preventive maintenance carried out every 300 days
