  "definition": "1. Chance that a given event will occur.\n\n2. The proportion (on a scale of 0 to 1) of cases for which a particular event occurs. Zero indicates the event never occurs and one indicates the event always occurs.\n\n3. Depending on philosophical perspective: (a) The frequency with which we obtain samples within a specified range or for a specified category (e.g., the probability that an average individual with a particular mean dose will develop an illness). (b) Degree of belief regarding the likelihood of a particular range or category. [FAO/WHO 2003b]\n\n4. A probability assignment is a numerical encoding of the relative state of knowledge. (SRA 2004)\n\n5. The subjective assignment of likelihood of future events; or the frequency of occurrence of an experimental or observations outcome. It refers to the uncertainty or partial knowledge associated with decision-making. (FDA 2002)\n\n6. A basic concept that may be considered undefinable, expressing \"degree of belief.\" Alternatively, it is the limit of the relative frequency of an event in a sequence of n random trials as n approaches infinity: (Number of occurrences of the event) / n. (Last 1983)\n\n7. The chance that a particular event will occur given the population of all possible events. (RAIS 2004)",
