Question 297594
Answer with a fraction, decimal or percent. There are 20 marbles in a jar. 10 are red, 3 are blue, 4 are black and 3 are white. If you reach in and grab a marble, what is the probability that it is red and white
---
It can't be red AND white.
P(red and white) = 0/20 = 0
----
Red and White are called "mutually exclusive events".
