Would you provide the Median number of rolls before a 7-out in craps?
Mean of 8.5 is skewed by the very long roll counts and median better represents where 1/2 of the shooters get to before the 7-out.
Also, as a request, what would the various percentile rank rolls be... 80%tile, 90%tile?
Thank you for your help.

I failed to follow that rule
About half the time you get more than 4 rolls and the other half less than 4.
About 20% of the time you get 10 or more rolls
A little under 10% of the time you get 14 or more rolls
A little over 1% of the time you get 26 or more rolls
0.1% for 39 or more
0.01% for 52 or more
