Reliability engineering is a sub-discipline of systems engineering that emphasizes the ability of equipment to function without failure. Reliability describes the ability of a system or component to function under stated conditions for a specified period of time. Reliability is closely related to availability, which is typically described as the ability of a component or system to function at a specified moment or interval of time. It has been known from the experience that 4 % of hard disks produced by a computer manufacture are defective. Find the probability that … See more If the rate of failure for an item is twice a year, what is the probability that no failure will happen over a period of 2 years?
