what describes the likelihood that a given event will occur?\no probability\no percentage\no genotype\no…

Brief Explanations:

Probability is a measure of the likelihood of an event occurring. It is expressed as a number between 0 and 1, where 0 means the event will not occur and 1 means the event is certain to occur. Percentages are a way to express a proportion out of 100 but are not the term specifically for likelihood of an event. Genotype and phenotype are terms in genetics related to an organism's genetic makeup and observable traits respectively, and not related to event - likelihood.

Answer:

A. Probability
