M2C2A: Episode 6⅔: Pi: A three part mathematic

Me comenta mi Roaring Thunder, que me faltó publicar esta entrega, por lo que arreglo mi error y les comparto el episodio 6 dos tercios Smile
Is pi random?
Nobody knows, but it looks random enough.
First of all: though pi will never change, randomness is still valid.
Second: Let's try to approve or not approve randomness.
One of the properties of randomness is that there are an approximately equal number of appearances of each of the possibilities (here 1, 2, 3, 4, 5, 6, 7, 8, 9 and 0). If you check in the digits of pi, you'll find this property true. Want to check it? Try going to this page and use Ctrl+F. ✓
Another property of randomness, though identical to the first in concept, but referring to the sequences of digits is also something you can try in the page of the last hyperlink, and with some short sequences, you will find it also true. ✓
You may start calling pi random, but we're still not sure. We need to know more digits to see if no sequences appear in the total of all pi digits (after all, you'd never know if a house is a house if you check atom by atom). So final answer?
