An average of 73 people die each year in the US as the result of being struck by lightning, with Florida recording the highest number of fatalities. The chances of being struck (but not necessarily killed) by lightning are put at approximately 1 in 700,000 (.000001428). Assuming that the strikes are independent, how likely is it that you would be hit by lightning twice in your life? Discuss the appropriateness of the independence assumption and any other assumptions you make.
