Well, just think about the following. The probability of winning the jackpot in the national lottery is almost 1 in 14 millions.  So far, there are 105 confirmed cases of  swine flu all around the world, with a population of about 6.7 billions people. This means that the actual probability for you of contracting the virus is around 1 in 638 millions. Why don’t you actually go and buy a lottery ticket, then? Think.
