Understanding Probability Concepts

The video tutorial explains the concept of probability, emphasizing that probabilities range between 0 and 1. It clarifies that probabilities cannot be negative and discusses the likelihood of events using fractions. The tutorial addresses common misconceptions, such as the probability of unlikely events being zero, and explores improbable scenarios to illustrate the concept of very low probabilities.

What is the range of possible values for probability?

• Between 0 and 2

• Between 0 and 1

• Between -0.5 and 0.5

• Between -1 and 1

Why is the probability of the sun rising in the west not 0.25?

• Because the sun rises in the north

• Because 0.25 is too high for such an event

• Because the sun rises in the west

• Because 0.25 is too low for such an event
