Odds of getting struck by lightning – 1 in 500,000

Odds of winning the Powerball – 1 in 292.2 million

Odds of drowning in the bathtub – 1 in 685,000

You can find the chances of experiencing all kinds of events, health issues and what not. One exception popping into my head is when reading the fact sheet included with every prescription medication. You will find no hard number stating the chances of contracting any of the listed side affects. Hmmmmm.

So why are the number gurus unable to calculate these odds?
