Question

Find the theoretical probability of the event when rolling a standard number cube. P(1) P(1) = ______

Answer 1

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}}`

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}`
