Final answer:
The probability of getting an even number on a six-sided die is 1/2, because there are three even numbers (2, 4, 6) out of six possible outcomes.
Step-by-step explanation:
The question asks about the probability of getting an even number on the spinner. In Mathematics, especially in the topic of probability, we base such calculations on the total number of possible outcomes and the number of favorable outcomes. When you roll a fair, six-sided die, the sample space S = {1, 2, 3, 4, 5, 6}. To find the probability of an event, you divide the number of ways that event can occur by the total number of possible outcomes. For an even number, the favorable outcomes are 2, 4, and 6. Thus, there are three favorable outcomes.
Since there are six possible outcomes in total and three of them are even, the probability is 3/6, which simplifies to 1/2. Therefore, the correct answer to the question is (A) 1/2.
