Great video if you approach the sums using a tree diagram . However , could Bayes' theorem be used in the same examples, its hard to know when to use the formula or using a tree diagram ?
Conditional ones will not appear on the foundation paper. You need to check the language carefully to determine if the probabilities change. Another thing is where it comes in the paper. If it is early on it will likely be dependent, later on will almost certainly be conditional.
