Final answer:
To find the probability of selecting an even number, divide the number of favorable outcomes by the total number of possible outcomes.
Step-by-step explanation:
To find the probability that the number selected is even, we need to determine the number of favorable outcomes and divide it by the total number of possible outcomes.
Given that there are 12 possible numbers on each die, and we are tossing two dice, the total number of possible outcomes is 12 * 12 = 144.
Out of these 144 outcomes, there are 72 outcomes where both dice show an even number (2, 4, 6, 8, 10, or 12).
Therefore, the probability of selecting an even number is 72/144 = 0.5.
