Let X denote the time to failure (in years) of a certain hydraulic component. the pdf Of X is fix) 32/(x + b. d. Verify that nx) is a legitimate pdf. Determine the cdf. Use thc result of part (b) to calculate thc probability that time to failure is between 2 and 5 years. What is the expected time to failure? If the component has a salvage value equal to 4 x) when its time to failure is x, what is the expected salvage value?
