How many 3's and 9's are in the first million digits of pi?

There are 70,674 3's in the first million digits of pi. * * * * * There are 100,230 3s and 100,106 9s. Since the decimal representation of pi is essentially random, the number of times any digit appears should be approximately 10% of the total number of digits. So, for a million digits, there should be around 100,000 of any digit so it should have been immediately apparent that the previous answer was extremely unlikely. In fact it was incorrect to a very large degree!
