comment How many $0$s does the number $30!$ have?
If you have $n!$, the product $1\cdot 2 \cdot 3 .... n$ will have more factors of 5 than factors of 2. So every factor of 5 contributes a zero to the end of $n!$. Do you see it now?

comment How to find a random axis or unit vector in 3D?
Indeed true. The volume of the unit sphere shrinks fast in high dimesions, but the OP only was interested in the three-dimensional case.
