Answer
0.167
Explanation
P(1) means: probability of rolling a 1 when rolling a standard number cube.
Probability is computed as follows:
![p=\frac{number\text{ of favorable outcomes}}{total\text{ number of outcomes}}](https://img.qammunity.org/2023/formulas/mathematics/college/g474isq3pkq453ju3ikpq71wgp0kvasdjv.png)
There are 6 total possible outcomes when rolling a number cube, and only one of them is a 1. Therefore the probability of rolling a 1 is:
![\begin{gathered} P(1)=(1)/(6) \\ P(1)=0.167 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/rutqr63oavfy3cp01l05xlvemhx9ii03p3.png)
