Probability Part 1: Rules and Patterns: Crash Course Statistics #13

Today we’re going to begin our discussion of probability. We’ll talk about how the addition (OR) rule, the multiplication (AND) rule, and conditional probabilities help us figure out the likelihood of sequences of events happening - from optimizing your chances of having a great night out with friends to seeing Cole Sprouse at IHop!

    At 3:52, I think what Adriene meant should be "Since P(tails and 6) is not equal to zero, these two events are not mutually exclusive" instead of "Since P(tails or 6) is not equal to zero,..."

    I think that when calculating the probability of P(A or B), we shouldn't calculate the probability of P(A and B) at all. So I think the formula should be like this: P(A or B) = P(A) + P(B) - 2P(A and B). That way, we can calculate the probability of only A or B occurring. The video says P(A or B) = P(A) + P(B) - P(A and B). Maybe our definition of the word 'or' is different? Please correct me if I'm wrong.
