Sagot :

Sure, let's break down the steps for understanding the given answers to the question based on the provided data.

We need to look at the following:
- The total number of households surveyed.
- The number of households with a specific number of children under the age of 5.

The survey data is as follows:
[tex]\[ \begin{tabular}{cc} \hline Number of Children (under 5) & Number of Households \\ \hline 0 & 17 \\ 1 & 13 \\ 2 & 16 \\ 3 & 2 \\ 4 & 2 \\ \hline \end{tabular} \][/tex]

To solve the problems:

### Part (a)
What percentage of households has two children under the age of 5?

1. Total number of households surveyed is the sum of all the households:
[tex]\[ 17 + 13 + 16 + 2 + 2 = 50 \][/tex]

2. The number of households with two children under the age of 5 is 16.

3. To find the percentage:
[tex]\[ \left( \frac{{\text{Number of households with 2 children}}}{{\text{Total number of households}}} \right) \times 100 \][/tex]
[tex]\[ \left( \frac{16}{50} \right) \times 100 = 32\% \][/tex]

Therefore, the percentage of households that have two children under the age of 5 is [tex]\(32\%\)[/tex].

### Part (b)
What percentage of households has one or two children under the age of 5?

1. The number of households with one child under the age of 5 is 13.
2. The number of households with two children under the age of 5 is 16.

3. Combine these two figures to get the total number of households with one or two children:
[tex]\[ 13 + 16 = 29 \][/tex]

4. To find the percentage:
[tex]\[ \left( \frac{{\text{Number of households with 1 or 2 children}}}{{\text{Total number of households}}} \right) \times 100 \][/tex]
[tex]\[ \left( \frac{29}{50} \right) \times 100 \approx 58\% \][/tex]

Therefore, the percentage of households that have one or two children under the age of 5 is approximately [tex]\(58\%\)[/tex].

To summarize, the answers are:
- The percentage of households with two children: [tex]\(32\%\)[/tex]
- The percentage of households with one or two children: [tex]\(58\%\)[/tex]
