Flip the coin…
I always loved those coin tricks and wondered how it happened. While making the coin magically disappear is definitely a mind trick (will talk about that too) but the coin flipping is mathematical. Here is an easy one, I flipped two quarter-coins and immediately announced that one came out as head. What is the chance that the second coin will also be a head?
If you were in Las Vegas would you bet on head or tail for the second coin? Have fun 🙂
