Question: what is the difference between biased and unbiased coin?
Answer: Unbiased coin has equal probability of Heads or Tails. If you throw the coin a million times, you will get 500,000 heads and 500,000 tails. A biased coin has a higher probability of heads or tails. ... e.g, 1 side heavier than the other so that the coin falls on the heavier side.
