Explanation:

Step1: Find total adults prefer newspapers

Add the number of registered and non - registered adults who prefer newspapers. $35 + 41=76$.

Step2: Find number of registered adults prefer newspapers

The number of registered adults who prefer newspapers is 35.

Step3: Calculate relative frequency

Relative frequency = $\frac{\text{Number of registered adults who prefer newspapers}}{\text{Total adults who prefer newspapers}}$. So, $\frac{35}{76}\approx0.46$.

Answer:

$0.46$
