Shark Statisitics Misleading

[-Demosthenes-]

This is from a "shark quiz" on msn. It starts with this:

But according to the International Shark Attack File, in 2004, for example, there were only 61 unprovoked shark attacks on humans, 30 of which occurred in the United States. With a U.S. population of about 300 million, this means the odds of being attacked by a shark in the United States are roughly 1 in 10 million.

 

A shark attack is obviously more likely if you are in the water. It says 30 people got attacked so it's 1 in 10 million in the US who has gotten attacked. But for people out of the water and not near the ocean it would be about zero and if you are in the water it would be much greater (30 in however many are in the ocean in the year).. If you average them then you get 1 in 10 million, is that a far number?

It would be better if they had an average number of people who go to beaches every year, and based their odds on that.
