Event that corresponds to an impossible outcome of a random experiment.
This event will never occur.
This event will never occur.
Empty subset of the set of possible outcomes of a random experiment.
Property
The probability of an impossible event is 0.
If the experimental probability of an event in a random experiment is close to 0, we say that this event is nearly impossible.
Examples
- We are drawing a ball from a bag in which there are 100 black balls. The event that consists of drawing a white ball is an impossible event.
- We are drawing a ball from a bag in which there are 99 black balls and one white ball. The event that consists of drawing a white ball is a nearly impossible event.
