Understanding Probability

The video tutorial introduces the concept of probability, explaining how it is used to describe the likelihood of events. It covers the probability scale, expected versus real outcomes, and provides formulas for calculating probability. The tutorial also discusses how to investigate probability through relative frequency, using examples like coin tosses. It concludes with a call to action for viewers to engage with the content.

In probability, what is the term used to describe the actual results of an experiment?

• Real outcomes

• Expected outcomes

• Theoretical outcomes

• Hypothetical outcomes

What is the formula for calculating probability?

• Number of total outcomes minus favorable outcomes

• Number of favorable outcomes multiplied by total outcomes

• Number of total outcomes divided by favorable outcomes

• Number of favorable outcomes divided by total outcomes

What is relative frequency?

• The ratio of favorable outcomes to obtained outcomes

• The ratio of total outcomes to obtained outcomes

• The ratio of obtained outcomes to total outcomes

• The ratio of favorable outcomes to total outcomes
