\hline Number Rolled & Frequency \\
\hline 1 & 11 \\
\hline 2 & 16 \\
\hline 3 & 14 \\
\hline 4 & 20 \\
\hline 5 & 12 \\
\hline 6 & 17 \\

\end{tabular}

Which statements below represent the situation? Select three options.

A. The relative frequency of rolling a 4 is [tex]\frac{2}{9}[/tex].
B. The experimental probability of rolling a 3 is greater than the theoretical probability of rolling a 3.



Answer :

Let's analyze the given data and interpret the results step-by-step. The table provides the frequency of each number rolled on a number cube.

| Number Rolled | Frequency |
|---------------|-----------|
| 1 | 11 |
| 2 | 16 |
| 3 | 14 |
| 4 | 20 |
| 5 | 12 |
| 6 | 17 |

First, we calculate the total number of rolls:

Total rolls = 11 + 16 + 14 + 20 + 12 + 17 = 90

Next, let's find the relative frequency of rolling a 4:

Relative frequency of rolling a 4 = Frequency of 4 / Total rolls
= 20 / 90
= 0.2222222222222222

Converting 0.2222222222222222 to a fraction, we get:
0.2222222222222222 = 2/9

So, the relative frequency of rolling a 4 is indeed [tex]\( \frac{2}{9} \)[/tex].

Now, let's move on to the experimental probability of rolling a 3:

Experimental probability of rolling a 3 = Frequency of 3 / Total rolls
= 14 / 90
= 0.15555555555555556

The theoretical probability of rolling any specific number on a fair six-sided die (number cube) is calculated as:

Theoretical probability of rolling a specific number = 1 / 6
= 0.16666666666666666

Finally, we compare the experimental probability of rolling a 3 to the theoretical probability:

0.15555555555555556 (experimental) < 0.16666666666666666 (theoretical)

Thus, the experimental probability of rolling a 3 is not greater than the theoretical probability of rolling a 3.

Summarizing the results:

1. The relative frequency of rolling a 4 is [tex]\( \frac{2}{9} \)[/tex].
2. The experimental probability of rolling a 3 is not greater than the theoretical probability of rolling a 3.

Based on the analysis, it seems like these are the most relevant and true statements for this situation:

- The relative frequency of rolling a 4 is [tex]\( \frac{2}{9} \)[/tex].
- The experimental probability of rolling a 3 is not greater than the theoretical probability of rolling a 3.
