The probability of flipping a coin and getting heads is determined by considering the total possible outcomes and the favorable outcomes. When flipping a standard coin, there are two possible outcomes: heads or tails. Since these outcomes are equally likely, the probability of obtaining either heads or tails can be calculated by taking the number of favorable outcomes (which is 1 for heads) and dividing it by the total number of outcomes (which is 2).

Thus, the calculation for the probability of getting heads is:

Probability of heads = Number of favorable outcomes / Total number of outcomes = 1/2.

This means that there is a 50% chance of getting heads when you flip a coin, which aligns with the correct answer. Options representing fractions such as 1/4, 1/3, and 1/5 do not accurately reflect the simple scenario of a coin flip, as they indicate probabilities that are inconsistent with the two equally likely outcomes of heads or tails.
