Quizplus · Accepted Answer

The probability of getting 1 or 2 heads when flipping a coin three times can be calculated by considering all possible outcomes. There are 8 total outcomes (HHH, HHT, HTH, THH, HTT, THT, TTH, TTT), and 6 of these outcomes contain either 1 or 2 heads (HHT, HTH, THH, HTT, THT, TTH). Therefore, the probability is 6/8 or 3/4, which simplifies to 0.75 or 75%. However, the provided options seem to imply a misunderstanding in the calculation or the presentation of the question as they do not match the correct calculation based on the usual interpretation of such a problem. Given the options, none directly reflects the accurate calculation for the scenario typically considered (flipping a coin three times). There might be a misinterpretation in the question setup or answer choices.
