The video tutorial introduces probability, distinguishing it from statistics, and explores its historical roots. It defines key probability concepts such as sample space and events, and demonstrates the use of tree diagrams and counting principles. The tutorial covers different types of probability, including classical, empirical, and subjective, and explains the law of large numbers and the use of complements in probability calculations.

What is the primary difference between probability and statistics?

• Probability and statistics are the same.

• Statistics is a subset of probability.

• Probability deals with random processes, while statistics deals with data.

• Statistics deals with random processes, while probability deals with data.
