Question

Hi, I play Wordle with a couple friends and we noticed that all the answers for the last 10 days contained an O. What is the probability that all the answers would contain an O for 10 days in a row? 56% of English words contain an O and Wordle chooses answers from a list of 2315 words. Thanks!

Answer 1

Assuming that the selection of words that Wordle uses is similar to the full language, so 56% of Wordle-words have at least one O, and assuming the selection is random and independent, the probability would just be (.56)\^10, approximately .3%.

​

If those assumptions aren't true, you'd need a lot more information, but .3% seems like a very good estimate.
