Document Summary
Conditional probabilities- focus on just one group of objects and imagine taking a random sample from that group alone. Associated- events are associated (dependent on each other) when the conditional probabilities change depending on what variable the event is conditioned on. The probability drawing a queen, given that you drew a queen earlier in the game. The chances of drawing a queen at the beginning of the game was 4/52. In the next turn, the probability of drawing a second queen is 3/51. Knowledge that event b occurred does not change the probability of event a occurring. Sequence- events that take place in a certain order. Rule 6: the probability of a given b (associated events) P (a|b) = p (a and b) / p(b) P(a and b) = p(b) x p(a|b)
