ABSTRACT
What are your chances of being in an auto accident and being struck by lightning on the same day? Let's suppose each of these accidents happens at the rate of one every thousand days, just to use round numbers and keep the waters from being muddied by too much arithmetic. Then I hear the mathematicians among you saying that the chance of experiencing both disasters on the same day is found by multiplying, so that the answer is one in a million. Right? Well, yes and no.
