A poll reported that 52% of people wear a seat belt.
If 4 people are selected at random, find the probability that
none wear their seat belt. Give your answer as a decimal rounded to two decimal places.
~~~~~~~~~~~~~~~~

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 =  = 0.0530.


Round it as you want.

Solved.
