Is rarer than to all the other months of the year (under the condition of uniformity)of course.
When Bob says that (quoting):
*** ...he said my approximate formula [dividing the year in 12 months each with 30 days] was wrong because I didn´t count the number of days of each month.***
Now I call the attention of the Readers by he Bob´s follow-up:
***...The 1/12 approximation of the 2nd person born on the same MONTH as the randomly chosen 1st is no different from 1/365 used as the aprox. probability of the same person on the same day ***
This is NECESSARY and SUFFICIENT to the Readers decide who is RIGHT
The length of time DAY is the same all over the year, the MONTHS (because have number of days) have different lengths.
I scarcely understand how Bob can assume that
___to find at least two persons born on FEBRUARY has the same probability than to find at least two persons born on (say) December.
