Hi WIkiacon

Not quite. The first quartile refers to the cumulative probability. It means that you should expect a non-12 egg to occur in 11 tries or less - about one quarter of the time.

Median: About half the time, you will get a non-12 egg in 26 attempts or less.

Half the time, it will take you 27 o r more tries.

Hope this helps.
