contingent

adj. dependent upon; possible; accidental, happening by chance

n. reinforcement, detachment of troops; representative group, delegation

In philosophy and logic, contingency is the status of facts that are not logically necessarily true or false. Contingency is opposed to necessity: a contingent act is an act which could have not been, an act which is not necessary (could not have not been). Contingency differs from possibility, in a formal sense, as the latter includes statements which are necessarily true as well as not necessarily false, while a statement can not be said to be contingent if it is true necessarily.
