As you enjoyed my last piece of maths...

Well hello to all my new followers! Hope you like $\LaTeX{}$ as i'm particularly fond of it and so you will see it all over my blog. My exams are finally over for this semester, and as a treat, I am going to show you another question I had to answer! However its too late tonight and I have a 9am tomorrow..... So heres a question to keep you all intrigued...


I have two children, and at least one of them is a son. What is the probability that the other is also a son?

Ugh... statistics was boring. But I'd say it's *greater* than 50%, since you're saying "at least" one of your kids is a boy.

The "at least" portion leads me to believe it's more than a neutral, even chance.

Could be completely wrong though.

I cant solve this!

Pretty sure that probability isn't influenced by the first son. So it should still be roughly 50%

nice blog idea

Shouldnt it still be %50? Although the odds of having a son is a little higher than having a daughter due to the Y chromosome being lighter and therefore faster but oh well =)

Hmmm, i would think it would be around 60%?
Great blog, maybe I'll even learn stuff from here.

If the answer turns out to be anything other than 50% I will be very upset :P

50% ?

I have actually used LaTeX for work. That stuff is amazing. As for the question, 100%. You didn't specify which other, and at least one of them is a boy. Cookie for me?

Also, following. :)
