The probability for any outcome is its proportion of all the possible outcomes. Probability is calculated as the number of outcomes A divided by total number of possible outcomes and can be represented as a decimal, fraction, or percentage (Gravetter et al., 2021). When flipping a coin, there are two possible outcomes total, heads and tails. If A = heads and there is one heads, the probability is ½, .50, or 50%. Therefore, your friend is not correct in saying you are more likely to get a heads than a tails on a single flip. Further, this probability will never change despite how many times a coin is flipped. So, if tossing a fair coin an infinite number of times, we can still expect the probability of landing on a heads to be 1/2.

Class, is there a situation where the number of trials does change the probability of a certain situation?
