... What a relief! There is only a 14% chance Joe has the disease, even though the test came back positive! The issue here is that the false-positive and false-negative percentages are in fact high, relative to the occurrence of the disease. You can draw a tree diagram to illustrate the cases, first bra ...

... Almost everyone says that HTHTTH is more probable, because TTTHHH does not “look random.” In fact, both are equally likely. That heads and tails are equally probable says only that about half of a very long sequence of tosses will be heads. It doesn’t say that heads and tails must come close to alte ...

... Example: (Continue with the light problem) Suppose at an intersection, we will meet a green light with a chance of 35% and a yellow light with a chance of 50%. Question: What is the probability of meeting a green light on Monday and Tuesday? Solution: Denote A={green on Mon} B={green on Tue} Then A ...
