Excuse me for a pedantic correction. It would be 25% if friday, shabbat,
monday and wednesday were equally likely in the first place, but they aren't
because of the dehiyot of rosh hashana. "Lo Ido Rosh" makes the 5th of Iyar
on a wednesday when the molad of tishrei is on either friday or shabbat, so
the total chance is 2 in 7, not 1 in 4, i.e. about 28.5%. (The effects of
Molad Zaken cancel out, and the other dehiyot aren't a factor here).
