Answer :

Sure! Let’s go through the solution step-by-step, based on the problem presented:

### (1) Construct a Frequency Table for the Data:
The table provided shows the outcomes and their respective frequencies of the spins. Here is the frequency table:

[tex]\[ \begin{array}{|c|c|} \hline \text{Outcome} & \text{Number of Spins} \\ \hline 1 & 13 \\ 2 & 9 \\ 3 & 24 \\ 4 & 7 \\ 5 & 11 \\ 6 & 8 \\ 7 & 10 \\ 8 & 5 \\ 9 & 7 \\ 10 & 6 \\ \hline \end{array} \][/tex]

### (2) Experimental Probability of Spinning a 5:
The experimental probability of spinning a number is the number of times that outcome occurs divided by the total number of spins. Here, we want the probability of spinning a 5.

Number of spins of 5 = 11 \
Total number of spins = 100

So,
[tex]\[ \text{Experimental Probability of spinning a 5} = \frac{11}{100} = 0.11 \][/tex]

### (3) Experimental Probability of Spinning a 3:
Similarly, we calculate the probability of spinning a 3.

Number of spins of 3 = 24 \
Total number of spins = 100

So,
[tex]\[ \text{Experimental Probability of spinning a 3} = \frac{24}{100} = 0.24 \][/tex]

### (4) Experimental Probability of Spinning a Multiple of 2:
The multiples of 2 in the given outcomes are 2, 4, 6, 8, and 10.

Number of spins of 2 = 9 \
Number of spins of 4 = 7 \
Number of spins of 6 = 8 \
Number of spins of 8 = 5 \
Number of spins of 10 = 6

Total number of spins for multiples of 2 = 9 + 7 + 8 + 5 + 6 = 35 \
Total number of spins = 100

So,
[tex]\[ \text{Experimental Probability of spinning a multiple of 2} = \frac{35}{100} = 0.35 \][/tex]

### (5) Experimental Probability of Spinning a Number Below 6:
The numbers below 6 are 1, 2, 3, 4, and 5.

Number of spins of 1 = 13 \
Number of spins of 2 = 9 \
Number of spins of 3 = 24 \
Number of spins of 4 = 7 \
Number of spins of 5 = 11

Total number of spins for numbers below 6 = 13 + 9 + 24 + 7 + 11 = 64 \
Total number of spins = 100

So,
[tex]\[ \text{Experimental Probability of spinning a number below 6} = \frac{64}{100} = 0.64 \][/tex]

### (6) Theoretical Probability of Spinning a 2:
In a 10-sector spinner, each outcome is equally likely. Hence, the theoretical probability of any specific outcome (such as spinning a 2) is:

[tex]\[ \text{Theoretical Probability of spinning a 2} = \frac{1}{10} = 0.1 \][/tex]

In summary:
1. Frequency table is as provided.
2. Experimental probability of spinning a 5: [tex]\(0.11\)[/tex]
3. Experimental probability of spinning a 3: [tex]\(0.24\)[/tex]
4. Experimental probability of spinning a multiple of 2: [tex]\(0.35\)[/tex]
5. Experimental probability of spinning a number below 6: [tex]\(0.64\)[/tex]
6. Theoretical probability of spinning a 2: [tex]\(0.1\)[/tex]
