The correct Answer is:
To find the probability of getting an even number on each die when a die is rolled two times (or two dice are rolled together), we can follow these steps: ### Step 1: Identify the total outcomes When rolling two dice, each die has 6 faces. Therefore, the total number of outcomes when rolling two dice is: \[ \text{Total Outcomes} = 6 \times 6 = 36 \] ### Step 2: Identify the favorable outcomes The even numbers on a standard die are 2, 4, and 6. Thus, for each die, there are 3 even numbers. When rolling two dice, we need both dice to show an even number. The favorable outcomes can be calculated as follows: - For the first die, there are 3 choices (2, 4, or 6). - For the second die, there are also 3 choices (2, 4, or 6). Thus, the total number of favorable outcomes is: \[ \text{Favorable Outcomes} = 3 \times 3 = 9 \] ### Step 3: Calculate the probability The probability of getting an even number on each die is given by the ratio of the number of favorable outcomes to the total number of outcomes: \[ \text{Probability} = \frac{\text{Favorable Outcomes}}{\text{Total Outcomes}} = \frac{9}{36} \] ### Step 4: Simplify the probability Now, we can simplify the fraction: \[ \frac{9}{36} = \frac{1}{4} \] ### Final Answer The probability of getting an even number on each die is: \[ \frac{1}{4} \] ---
