No, disjoint events are never independent.

Explanation:

The word disjoint means that the described events cannot occur at the same time. That is, if one event occurs, the other event(s) cannot occur. This means that knowing whether or not one event occurred gives you information about whether or not the other event(s) occurred. Since the probability of one disjoint event occurring depends on whether or another event occurred, the events are dependent.
