<pre>
If 52% of people wear a seat bell, then 48% do not wear.


So, the probability that randomly selected passenger/driver does not wear his or her belt is 0.48.


Then the probability that of 4 randomly selected people (drivers or passengers) none wear their
seat belt is

    P = {{{0.48^4}}} = 0.0530.


Round it as you want.

Solved.
