2. Components are existing in ONE of TWO STATES: 1 WORKING STATE with probability R 0 FAILURE STATE with probability F R+F = 1 RELIABLEFAILURE F R Selecting a random number 0<= X<= 1 X lies in the green zone, the component is in State 1 (Working) Otherwise, the component in State 0 (Failure)

3. How to Generate a Sample of Time To Failure (TTF) of a Components By Monte Carlo Simulation Experiment TTF Failure Probability Selecting a Random Number 0<= X <= 1 Put X= Failure Probability anf find TTF CONSTANT FAILURE RATE Weibull Distribution
