Answer

Explanation:

Step1: Recall joint - relative frequency formula

Joint relative frequency = $\frac{\text{Frequency of the joint category}}{\text{Total frequency}}$

Step2: Identify relevant frequencies

The frequency of school children who plan to attend camp and have swimming lessons is 42. The total frequency of all children surveyed is 96.

Step3: Calculate joint - relative frequency

Joint relative frequency = $\frac{42}{96}= 0.4375$

Step4: Convert to percentage and round

$0.4375\times100 = 43.75%$. Rounding to the nearest percent gives 44%.

Answer:

44%
