SUMMARY
The probability of selecting the correct answer at random from four non-identical choices is 25%, as there is one correct answer among four options. However, if two of the answers are identical, the probability of selecting the correct answer increases to 33.33% (1/3). This paradox illustrates the complexities of probability in multiple-choice questions.
