Odd Facts: Feet

Consider this fact:

Most people have an above average number of feet.

How can this be? People have two feet. Do they? Consider …

The norm for humans is to be born with two feet. So far so good. A vanishingly small number (maybe, say, 1 in a million, probably fewer) are born with 3 or more feet. But for a variety of reasons a significant number will be born with only 1 foot or even no feet. And of course some people unluckily go on to lose a foot or even both feet. I don’t know the real numbers but let’s guess, for the sake of example, that 1 in 100 people have only 1 foot and 1 in 1000 have no feet at all.

So what is the average number of feet on a human? It clearly isn’t two! Using the above figures by way of example the average number of feet is 1.988 per person. Yes that’s less than 2! But for every million people 988,999 have two feet. So it is correct to say that most people, indeed the vast majority of people, have more than the average number of feet.

Amazing what simple statistics reveal and the logic we all pass over every day!
