Yay me!

I could probably write an entire blog entry about the blogs and podcasts I read and listen to regularly. But I’d like to talk about one in specific.

I have been listening to The Skeptics Guide to the Universe for about two years now. It’s a weekly conversational style between five well-known people in the science/skepticism community. (Steven Novella, Jay Novella, Bob Novella, Evan Bernstein, and Rebecca Watson)

One of the regular features of this show, is a listener-response segment called “Who’s That Noisy”. It used to be that they’d play a sound clip of something and challenge their listeners to guess what it is. Late last year, they switched the format from universally sound clips, to also putting math and logic puzzles into the mix as well.

I have never been able to figure out what the sound clips are, so I appreciated the expansion into logic puzzles.

This year, they added a new bit to this segment: if you’re among the correct guesses to the puzzle/sound, they will put your name into a drawing and pick one of those correct guesses at random. At the end of the year, all of the randomly chosen names will be thrown into one final drawing, the winner of whom will get to have a spot on the show itself.

And I got last week’s puzzle correct, so my name was in the drawing. And my name was chosen from among the correct guesses! More news on this to come.

What was the puzzle, you might ask? It’s pretty straightforward:

If I have two children, one of whom is a boy born on a Tuesday, what are the odds that I have two boys?

Scroll down for the answer…

13/27. We’ve got the following permutations for two children:
The first child is the boy born on a Tuesday and the second child is a boy born on any day of the week. (7 possibilities)
The first child is the boy born on a Tuesday and the second child is a girl born on any day of the week. (7 more possibilities)
The first child is a girl born on any day of the week and the second child is the boy born on a Tuesday. (7 more possibilities)
The first child is a boy born on any day of the week other than Tuesday (The Tuesday would have been captured in the first grouping) and the second child is the boy born on a Tuesday. (6 possibilities).
Going through all of those possibilities, there are 27 possible permutations of children where one was a boy born on a Tuesday, of which 13 have two boys…..

Now we just need to see if I win the drawing at the end of the year. We shall see….
