Question 1149171: A system engineer is interested in assessing the reliability of a rocket
composed of three stages. At take off, the engine of the first stage of the
rocket must lift the rocket off the ground. If that engine accomplishes its
task, the engine of the second stage must now lift the rocket into orbit.
Once the engines in both stages 1 and 2 have performed successfully, the engine of the third stage is used to complete the rocket’s mission. The reliability of the rocket is measured by the probability of the completion of the mission.
If the probabilities of successful performance of the engines of stages 1, 2 and 3 are 0.99, 0.97 and 0.98, respectively, find the reliability of the rocket. Answer by ikleyn(52754) (Show Source):
