Probability assessment

unit for the arithmetic difference of two percentages

analysis with risk acceptance criteria or other decision parameters

probability distribution that would express one's uncertainty before some evidence is taken into account

A micromort (from micro- and mortality) is a unit of risk defined as a one-in-a-million chance of death. Micromorts can be used to measure the riskiness of various day-to-day activities. A microprobability is a one-in-a million chance of some event; thus, a micromort is the microprobability of death. The micromort concept was introduced by Ronald A. Howard who pioneered the modern practice of decision analysis.
