Heads or Tails? Careful: It's not 50-50 The phrase "coin toss" is a classic synonym for randomness. But since the 18th century, mathematicians have 1 that even fair coins tend to land on one side slightly more often than the other. Proving this tiny bias, 2 , would require hundreds ...

However you get back to zero, you’ll have to flip the coin 2N times (you can’t have an equal number of heads and tails if you flip an odd number of times). Now say you have a series of tallies that starts at zero, then stays greater than or...
If you flip a fair coin 10 times, what is the probability that it lands on heads exactly 4 times? What is the probability of getting 3 heads if a coin is tossed 5 times? A coin is tossed three times. What is the probability of the coin landing either h...
The audience then makes a series of free choices regarding how many coins they flip. They then choose a coin and cover it with their hand, while eliminating the rest of the coins. The magicians then reveals if that coin is heads or tails with perfect accuracy. The best part is that it...
