Oxford Probability Miscellany #2

Here's the link to my video on independence & mutual exclusivity:

Note, you'll encounter the notation P(B|A) which is read as "the probability of B given that A has already occurred". If you realize A has had no effect on B then you can conclude that A, B are independent. This is often stated as "A and B are independent if and only if P(B) = P(B|A)".

At 1:00 I intended to write the union symbol "U" of course.
