Webb26 mars 2024 · The conditional probability of A given B, denoted P ( A ∣ B), is the probability that event A has occurred in a trial of a random experiment for which it is known that event B has definitely occurred. It may be computed by means of the following formula: (3.3.1) P ( A ∣ B) = P ( A ∩ B) P ( B) WebbProbability tells us how often some event will happen after many repeated trials. You've experienced probability when you've flipped a coin, rolled some dice, or looked at a weather forecast.

WebbIn probability, we say two events are independent if knowing one event occurred doesn't change the probability of the other event. For example, the probability that a fair coin shows "heads" after being flipped is 1/2 1/2. What if we knew the day was Tuesday? Does this change the probability of getting "heads?" Of course not.

"WebbThe key to this question is finding the probability that Doug draws silk. In order for Doug to get silk, Maya first has to not get silk (5/6 chance) then Doug has to draw silk (1/5 chance). So this means that Doug has a (5/6)* (1/5) or 1/6 chance of drawing silk. If he has a 1/6 chance of drawing silk, then that means that he has a 5/6 chance ... " - Probability of 2 dependent events
