First Tanga Puzzle Published!

I’ve just had my first puzzle published on Tanga.com. It was an Easy One Word Wonder. Can you figure it out? The solution to this puzzle is a single word. Let me know if you need any help.

Any ideas?

Do You Have a Feel For Probability?

Here’s an old, but still tricky question of probability.  You will find it discussed many places on the Net, but give yourself some time to think about it before looking elsewhere.  Be warned that looking elsewhere may only lead you to differing conclusions anyway…
