This video tutorial explains the concept of probability, which is the chance of an event occurring. It covers simple events, outcomes, and how probability can be expressed as a fraction, decimal, or percent. The tutorial introduces the probability scale from 0 to 1, where 0 is impossible, 1 is certain, and 0.5 is equally likely. Examples include calculating the probability of rolling a six on a cube, tossing a penny to get heads, rolling a 2, 3, or 4, and not rolling a six. The video concludes with a review of these concepts.

What is a simple event in probability?

• An event with one outcome or a collection of outcomes

• An event with no outcomes

• An event with multiple outcomes

• An event that is impossible
