**Transcription and Explanation for Educational Website**

---

The table and exercise shown here are part of a statistics problem focusing on the distribution of televisions in households within a small town. Below is a detailed explanation.

---

**The Number of Televisions per Household in a Small Town:**

| Televisions | Households |
|-------------|------------|
| 0           | 26         |
| 1           | 440        |
| 2           | 725        |
| 3           | 1402       |

---

### Task (a)

**Construct a Probability Distribution:**

To construct the probability distribution, calculate the probability \( P(x) \) for each value \( x \) (number of televisions), based on the frequency of households:

1. **Determine Total Households:** Sum up the households:
   \[
   26 + 440 + 725 + 1402 = 2593
   \]

2. **Calculate Probability for Each \( x \):**

   \[
   P(0) = \frac{26}{2593}
   \]
   \[
   P(1) = \frac{440}{2593}
   \]
   \[
   P(2) = \frac{725}{2593}
   \]
   \[
   P(3) = \frac{1402}{2593}
   \]

3. **Probability Values Rounded to Three Decimal Places:**
   - \( P(0) = 0.010 \)
   - \( P(1) = 0.170 \)
   - \( P(2) = 0.280 \)
   - \( P(3) = 0.541 \)

---

### Task (b)

**Graph the Probability Distribution Using a Histogram:**

Below are three histogram options labeled A, B, and C. Each shows different distributions. Choose the correct one based on the calculated probabilities.

- **Explanation of Histogram Options:**
  - **Option A:** Bars incorrectly distributed.
  - **Option B:** Correct distribution (matches calculated probabilities of \( P(x) \)).
  - **Option C:** Bars incorrectly distributed.

**Conclusion:** Option B is the correct histogram that represents the calculated probability distribution of televisions per household.

---

This concludes the explanation. Practice constructing probability distributions and interpreting graphical representations such as histograms to enhance your statistical analysis skills.
