Hail to thee, Sofia! (Posted on 2010-12-13) Difficulty: 2 of 5


Let p= 1/2*3/4*5/6*7/8..*99/100.

Is p bigger than, equal to or less than 0.1 ?

The famous Sofia Kovalevskaya (1850-1891) solved this problem allegedly in no time, when she was only twelve years old.

Please provide your answer without programming and without direct evaluation.

Thanks Charlie!

I've amended 1. As to 2, I thought that was simply gilding the lily, so didn't bother to mention it. But of course you are right to have pointed that out too.
