# DailyDirt: Pi Math

### from the urls-we-dig-up dept

National Pie Day is not actually March 14th (although it really should be, if only to make it more memorable). But here's to the number, not the delicious dessert.

### Re: Re: Re: Re: Pi

your example does not make much sense, there cannot be an infinitely long string of (essentially random) that does not contain and equally infinite of infinite sequences of numbers.

if you have a string of infinite numbers non-repeating (essentially random). you will have 1234567890 occurring an infinite number of time. NOT zero times.

if you want to proof, you can work it out yourself. or just look up the web page that has it.

with only 100 million digits of pi, you have a 0.995% chance of finding your 1234567890.

almost 1% in only 100 million.

so multiply the number of digits by 1000 and you will have 100% chance of finding your 10 digit sequence.

1000 times 100 million falls very short of infinite, 100% is still 100%.

in fact you would expect to find that sequence 10 times in your pi to 100 billion decimal places.

And I don't think 100 billion is very close to infinite, what do you think ???
