Answer:
<em>The approximate probability that a random vehicle is a passenger car is 74.67%</em>
Step-by-step explanation:
<u>Probability</u>
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:
p = 0.7467
p = 74.67%
The approximate probability that a random vehicle is a passenger car is 74.67%
