There are a total of 456 vehicles, of which 214 are cars. Thus the probability of selecting a car at random is:

214/456=46.93%.

There are a total of 456 vehicles going over the two bridges, with 230 going over the Golden Gate Bridge. Thus, the probability of selecting a vehicle at random that is going over the Golden Gate Bridge is:

230/456=50.44%
