Answer:

The approximate probability that a random vehicle is a passenger car is 74.67%

Step-by-step explanation:

Probability

The traffic engineer records 112 passenger cars, 18 light trucks, and 20 heavy trucks. The total of vehicles recorded is n=112+18+20 = 150.

We are required to find the probability that a randomly selected vehicle crossing the bridge is a passenger car. There are 112 passenger cars, thus the probability is:

[tex]\displaystyle p=\frac{112}{150}[/tex]

p = 0.7467

p = 74.67%

The approximate probability that a random vehicle is a passenger car is 74.67%
