Question

Quizplus · Accepted Answer

The fact that both eyes of a rat have to be the same color means that these eye colors are disjoint or mutually exclusive. It is impossible for a rat to have one blue eye and one brown eye, for example. Therefore, the eye colors are not independent or dependent. Empirical does not apply to this scenario as it refers to information that is based on observation and experiment, rather than a statistical concept like probability.
