And one minus the probability both …

Web1.15 Mean Time Between Failure. Mean time between failure (MTBF) is a prediction of the reliability of a product. Tests and statistical analysis of parts and components are performed to predict the rate at which a product will fail. It is one of the most common forms of reliability prediction and is usually based on an established analysis model. WebTI’s MTBF/FIT estimator search tool allows you to find generic data based on technology groupings to estimate these typical questions and shows conditions under which the rates were derived. Simply enter a part number, and the tool will present the data. All terms used in the tool and definitions can be found on our reliability terminology page.
