Question

A bag contains 25 marbles;10 black,13 red,and 2 blue. A marble is drawn from the bag at random.

a.) Explain why the events "getting a black marble" and "getting a red marble" are mutually exclusive.
b.)What is the probability of getting a red or a blue marble?
c.) A car approaching an intersection has a 0.1 probability of turning left and a 0.2 probability of turning right. Explain why the events are mutually exclusive. What is the probability that the car will turn?

Answer 1

For Part A:

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)
