Answer: Not very likely to get two consecutive drivers wearing seat belts.

Explanation:

From the question the report shows only 15% percent wear seat belts.

If 10 cars are selected at random the possibility of getting at least one wearing seat belt is

= 10 * 15/100

==> 1.5 out of 10

1.5, is not upto average of 10 it's just a bit above the zero mark. Which makes the chances of meeting at least one driver wearing seat belt low.

To get consecutive drivers wearing seat belts, would be even a lower possibility. This is so due to the fact that according to the records the chances of meeting a driver on seat belts is low, and the possibility of it happening in quick succession is going to be smaller, because overall percentage of drivers wearing seat belts is small.
