Somehow, I was wondering how many unique bingo cards were possible and decided to see if I could figure it out. I arrived at an answer, but it was monumentally wrong.
According to this wiki article,
https://en.m.wikipedia.org/wiki/Bing...#Randomization there are 552 septillion combinations.
That’s a hard number to wrap your mind around. The article states that if you could print a trillion of them per second, it would take 17,000 years to finish.
