A swindler once approached an honest man with a die. He handed him the die and told him about the bet. The die had six sides. If the man rolled a ONE, he wins, and gets back twice the amount of his bet. If not, the swindler would keep the bet.
"But...my chances are only one out of six," retorted the man.
"True," grinned the swindler, "But I'll give you three tries to get a one."
The man considered. Three tries, with each try having a 1/6 chance of winning. So his chances of winning is 1/2. Why not give it a try?
Is the bet really fair? If not, what are the chances of the man winning?View full teaser and answer

Since the horse is normal, how is this situation possible?View full teaser and answer

Below is a list of five countries, all with the vowels removed. Can you name them?
Remove a letter from each of the words below and rearrange the remaining letters to form new words. The 10 words will all fall into a certain category. For example, given the words DEAR, ANGRY, and RENEGE, you could drop the "A" in DEAR to get RED, drop the "N" in ANGRY to get GRAY, and drop an "E" in RENEGE to get GREEN. These would all fall into the category of "Colors".
If you're stuck, the hint will name the category. The tough part is getting all 10 words.
Hint: The category is insects.View full teaser and answer
