ARGGGGGGGGGGGGGGGGGGGGGGGRRRRRRRRRRRRRRRRRRHHHHHHHHHHHHHHHH!!!!!!!
Wow, it's my pet hate!
It is NOT 100%, 33% or 25%. The answer is 50%.
The events of "having child 1" and "having child 2" are independent events. What happened the first time will not affect what happens the second time. So, we are told that the first one is a boy. So that one is a boy. Now, we are worried about the second one. What happened with the first one is completly irrelevant. There is a 50% chance of it being a boy. 50% chance of it being a girl. 50% is the answer! I'll do the mathmatical working later if needed.
Have some of you not done probability in school yet?

Also, I guess that there really is a reason that some people use junk 30%/ 10% scrolls before using the one they want to o_o
They actually think that it helps......
