To solve this problem, we will use the following formula:
![P(event)=\frac{favorable\text{ outcomes}}{total\text{ outcomes}}.](https://img.qammunity.org/2023/formulas/mathematics/high-school/xfxly8e9cttuuzrotyrhmmq7c3r1gncseb.png)
Recall that in a 6-sided die, there are 3 sides that have a prime number:
![2,3,\text{ and}5.](https://img.qammunity.org/2023/formulas/mathematics/high-school/ghilw7h47da20tjwxnc37hi9icfxk9sao8.png)
Therefore, there are 3 favorable outcomes, and there are 6 outcomes in total.
Substituting the above values in the formula, we get:
![P(prime)=(3)/(6)=(1)/(2).](https://img.qammunity.org/2023/formulas/mathematics/high-school/j84g50cu9zjivou5mofeaibwyvkwxy2zmq.png)
Answer:
![P(prime)=(1)/(2).](https://img.qammunity.org/2023/formulas/mathematics/high-school/w4t7zg1g5z6tagjegmmcvyk2og6526qrwz.png)
