Probability and Planetary Concepts

The video tutorial introduces the concept of probability, explaining how it measures the likelihood of events occurring. It covers key vocabulary such as outcome, sample space, and event, using examples like dice rolls to illustrate these terms. Theoretical probability is discussed, showing how to calculate it by dividing favorable outcomes by possible outcomes. The tutorial also explains the complement of an event, which is the probability of the event not happening, and demonstrates how to calculate it. Overall, the video provides a foundational understanding of probability concepts and calculations.

What does a probability value of 0 indicate?

• The event is equally likely to happen or not.

• The event is impossible.

• The event is certain to happen.

• The event is very likely to happen.

What does a probability of 1 mean?

• The event is equally likely to happen or not.

• The event is certain to happen.

• The event is very unlikely to happen.

• The event is impossible.
