The Math Behind Coin Flipping (50/50 Probability)
In theoretical probability, a fair coin has an exact 50% probability (0.5) of landing on Heads and 50% on Tails. According to the Law of Large Numbers, as the total number of coin tosses increases, the observed frequency of Heads and Tails gets closer to the theoretical 50/50 split.
