Probability Concepts and Rules

The video tutorial covers essential probability formulas, including the addition and multiplication rules, and explains conditional probability. It demonstrates calculating probability distributions using dice and provides an example of conditional probability with cards. The tutorial concludes with a discussion on independent and disjoint events, emphasizing the importance of understanding these concepts in probability.

What is the formula for the probability of A or B?

• P(A) + P(B)

• P(A and B)

• P(A) * P(B)

• P(A) + P(B) - P(A and B)
