A biased coin is a coin that does not have an equal probability of landing on each side when flipped. For example, it may have a higher likelihood of landing on heads than tails due to an uneven weight distribution or design. This bias can be quantified, typically expressed as a percentage, indicating the probability of each outcome (e.g., a 70% chance of heads and a 30% chance of tails). Consequently, repeated flips of a biased coin will yield outcomes that reflect this skewed probability rather than the expected 50/50 results of a fair coin.
