The probability of getting any specific combination of heads and tails in 10 tosses is (1 / 2) 10, or 1 / 1024, since there are 2 10 (1024) possible combinations of heads and tails for 10 coin tosses. A coin has two sides, so there are two possible outcomes of a fair coin toss: heads (H) or tails (T). What is the probability of getting atleast 1 Head Solution: Total number of outcomes possible when a coin is tossed`=2` Hence, total number of outcomes possible when `2` That is, why is the probability of heads 1/2 for a fair coin? Since the coin toss is a physical phenomenon governed by Newtonian mechanics, the For example, when we toss the coin, the result will be either a head or a tail, but we cannot get both at the same time. Fair and instant results. The Coin Toss Probability Calculator calculates the theoretical odds of getting a certain number of heads or tails in a series of flips.
