A bag contains 25 marbles: 10 black, 13 red, and 2 blue. A marble is drawn from the bag at random. Why are the events “getting a black marble” and “getting a red marble” mutually exclusive?

Answer:

because both the sets are disjoint sets . u can’t draw a black one while drawing a red one and vice versa

A marble can have only one color, so you cannot choose a marble that is both black and red. Therefore the events are mutually exclusive (cannot happen simultaneously)
