Answer

Explanation:

Step1: Recall joint - relative frequency formula

Joint relative frequency = $\frac{\text{Frequency of the joint event}}{\text{Total number of data points}}$

Step2: Identify the frequency of the joint event and total number of data points

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

Step3: Calculate the joint - relative frequency

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

Step4: Convert to percentage and round

$0.4375\times100% = 43.75%$, rounded to the nearest percent is 44%

Answer:

44%
