Final answer:
The probability of rolling an even number on a normal die is 1/2.
Step-by-step explanation:
To find the probability of rolling an even number on a normal die, we need to determine the number of favorable outcomes and divide it by the total number of possible outcomes. A normal die has six faces, with three even numbers (2, 4, and 6) and three odd numbers (1, 3, and 5). Therefore, the probability of rolling an even number is 3/6, which simplifies to 1/2.
