To find the probability of rolling an odd number on a fair 6-sided number cube, we first need to identify the odd numbers on the cube. A standard 6-sided die has the following numbers: 1, 2, 3, 4, 5, and 6.
The odd numbers in this set are 1, 3, and 5. Therefore, there are a total of 3 odd numbers.
Next, we find the total number of possible outcomes when rolling the die. Since there are 6 sides on the die, there are 6 possible outcomes.
Now, we can calculate the probability using the formula:
Probability = (Number of favorable outcomes) / (Total number of outcomes)
In our case:
Probability of rolling an odd number = 3 / 6
This simplifies to:
1 / 2
So, the probability of rolling an odd number on a fair 6-sided number cube is 1/2, or 50%.
