Answer 1

To find the relative frequency for the event "spin a 1", you will use the formula:

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

From the table you provided:

• Frequency of spinning a 1 = 21
• Total number of trials = 75

Now, plug in the values:

$$\text{Relative Frequency}=\frac{21}{75}$$

Next, simplify the fraction:

$$\text{Relative Frequency}=\frac{21÷3}{75÷3}=\frac{7}{25}$$

Therefore, the relative frequency for the event "spin a 1" is:

$$\frac{7}{25}$$
