On a game show there are three closed doors – one hides a car and the other two conceal a goat. The contestant selects a door, which remains closed, and the host, knowing where the car is hidden, reveals a goat behind one of the remaining two doors. The contestant is then given the option to switch doors or stay with the one they originally selected. What should the contestant do to have the best chance of winning the car?
The contestant should switch doors, which doubles the chance of winning the car. Initially there is a 2/3 chance of picking a goat, but once the other goat is revealed, switching to remaining door gives the contestant a better chance of winning the car. This is known as the Monty Hall Problem and can be very unintuitive.
Frog. It only has four letters, removing the “r” leaves fog, which makes it hard to see. Changing the “r” to an “l” makes flog, a punishment I hope you’ve never experienced. Flog backwards is golf, a game some would call a punishment when you keep swinging away at the ball yet it remains perched on its little white tower of terror while the other golfers impatiently wait for you to tee off.
Alphabet (unfortunately there aren’t any actual dictionary words with every letter in the alphabet, so this gimmicky, somewhat unsatisfying answer has to suffice).
A train is a half mile long and is about to enter a 10 mile tunnel. If the train is traveling at 35mph, how long will it take for the entire train to make it through the tunnel, from the front of the train entering to the end of the train leaving the tunnel?
