If you flip a coin, what is the probability of getting heads?

When flipping a standard coin, there are two possible outcomes: heads or tails. Each outcome is equally likely to occur, meaning there are no biases affecting the result. The total number of outcomes is 2.

To find the probability of a specific outcome—in this case, getting heads—you divide the number of ways that outcome can occur by the total number of possible outcomes. Since there is only one way to get heads and two possible outcomes overall, the calculation becomes:

Probability of heads = (Number of ways to get heads) / (Total number of outcomes) = 1 / 2.

This calculation shows that the probability of obtaining heads after flipping the coin is 1/2, which corresponds to the choice provided. Therefore, the correct answer reflects the fundamental principle of probability related to equally likely events.
