On the other hand, taking an egg out of the fridge and boiling it does not influence the probability of other items being there.
If you have a recurring problem with losing your socks, our sock loss calculator may help you. To give a simple example – looking blindly for socks in your room has lower chances of success than taking into account places that you have already checked. Bayes' rule calculates what can be called the posterior probability of an event, taking into account the prior probability of related events.
The videos above are part of the Khan Academy’s unit on probability.Bayes' theorem is named after Reverend Thomas Bayes, who worked on conditional probability in the eighteenth century. Specialized content is developed through partnerships with NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT. Subject matter ranges from math, science and computer programming to history, art history, and economics. Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. Conditional probability tree diagram (~11 min). This video uses a tree diagram to work out the following conditional probability question: If someone fails a drug test, what is the probability that they actually are taking drugs?.This video uses conditional probability to see if events are independent or not. Conditional probability and independence (~4 min).Created by Brit Cruise, this video presents conditional probability visually using trees. Conditional probability with Bayes' Theorem (~5 min).These three videos, produced by Khan Academy, focus on conditional probability.
