The question asks to identify the number of children that occurred the least frequently and to calculate the percentage of this occurrence.

Step 1: Identify the least frequent occurrence

From the table:

• 0 children: 250 occurrences
• 1 child: 112 occurrences
• 2 children: 560 occurrences
• 3 children: 201 occurrences
• 4 children: 68 occurrences
• 5 or more children: 59 occurrences

The least frequent number is "5 or more" children with 59 occurrences.

Step 2: Calculate the percentage

To find the percentage, use the formula:

$\text{Percentage} = \left( \frac{\text{Frequency of least occurrence}}{\text{Total frequency}} \right) \times 100$

Calculating the total frequency:

$250 + 112 + 560 + 201 + 68 + 59 = 1250$

So, the percentage is:

$\text{Percentage} = \left( \frac{59}{1250} \right) \times 100 \approx 4.72\%$

Hence, the correct answer is: 5 or more, 4.72%.
