So how small is it then? (Posted on 2006-08-09) Difficulty: 3 of 5
In a magazine recently there was a discussion about probability.

The author asserted that the probability of the event in question was approximately

(1 - 10-21)1025

How small is this number?

Exponentiation is not associative.  The problem has a^(10^25) = a^10000000000000000000000000 which is not the same as (a^10)^25 = a^250
