I have now realized one of my few explicit life goals. It is: getting a 28 hand in cribbage. According to this page, there are 12 million 944 thousand 8 hundred possible cribbage hands, 7ty six of which can combine to make 28 points. So, depending on how you write it, the odds of getting such a hand are either 0.0006 or one in 15,028 or
6.65424541 × 10-5!
Have you ever done anything so improbable? (Existing doens't count because of the good old anthropic principle)
