Answer 1

To find the relative frequency for the event "spin a 2," you need to take the number of times "spin a 2" was the outcome and divide it by the total number of trials.

From the provided data:
- The frequency of spinning a 2 is 30.
- The total number of trials is 80.

The formula for relative frequency is:

\[
\text{Relative Frequency} = \frac{\text{Frequency of the event}}{\text{Total number of trials}}
\]

Now substituting the values:

\[
\text{Relative Frequency for "spin a 2"} = \frac{30}{80}
\]

Calculating this gives:

\[
\text{Relative Frequency for "spin a 2"} = 0.375
\]

Therefore, the relative frequency for the event "spin a 2" is **0.375**.
