comment The Three Princesses
@GregMartin, I reversed the genders to address your concern. Given the lack of historical commoditization of male progeny, this should address it, and doesn't harm the problem in any way.

revised “The Bachelorette Problem” (slightly adapted from Tao's Google+ account)
Some readers thought the original reinforced negative gender stereotypes, so I jut reversed the genders. Even if you think that unneeded, it seems like it can't possibly cause any harm, so why risk a fun problem being shut down?

revised Probability of first actor winning a “first to roll seven with two dice” contest?
Edited to clarify that P goes first. *Tried* to make title less ambiguous, but I bet someone else can improve the wording I came up with.

comment Monty hall problem extended.
As a side note, if you're trying to change the problem for the purpose of teaching it, (rather than just creating a fun variety,) you should have Monty reveal n-2 goats, where n=total doors at start. That still matches the original problem (he'd open 1 of the 3,) and it makes the correct answer (not switching) really obvious as N increases. "You pick 1 of 100 doors. He opens 98, revealing goats. Do you keep the one you picked, or switch to the other?" (See @Tony's answer below - I didn't before posting this, but it makes the same point. +1 to him.)
