Finally, the base-rate heuristic is a mental shortcut that helps us make a decision based on probability.

Psychology Definition of REPRESENTATIVENESS HEURISTIC: Psychological term in which people judge the probability of a hypothesis by ascertaining how well the hypothesis mimics available data. The scarcer an object or event is, the more value that thing holds. Representativeness is the extent to which an event is representative of its parent population. For this reason, the representativeness heuristic is exemplary of the conjunction fallacy.
