An independent surveyor is curious about the number of traffic lights drivers pass by on their way to work each day. The surveyor constructs the following partially completed table for the percentage distribution corresponding to the number of traffic lights drivers pass by each day on their way to work:

Number of traffic lights passed	0-2	3-5	6-8	9-11	12-14	15 or more
Percentage of drivers	6.7	8.8	?	20.2	24.1	24.5

Determine the probability that a randomly selected driver will pass by less than nine traffic lights on their way to work (3 decimal places).
