The probability that a randomly selected car along the same portion of the highway was a speeding sports car \boxed{0.182{\text{ or 18}}{\text{.2\%}}}.

Further Explanation:

The independent probabilities of two sets can be calculated as follows,

\boxed{P\left({A \cap B}\right)=P\left(A\right)\times P\left(B\right)}.

Here, A represents the first event and B represents the second event.

Given:

In traffic data there are 35 percent of automobiles.

There 52 percent of sports cars that are speeding on the highway.

Calculation:

Let A denote the event that a vehicle travelling on the highway is an automobile.

The probability of event A can be calculated as follows,

\begin{aligned}P\left(A\right)&=35\%\\&=0.35\\\end{aligned}

Let B denote the event that an automobile is a speeding sports car.

The probability of event B can be calculated as follows,

\begin{aligned}P\left(B\right)&=52\%\\&=0.52\\\end{aligned}

The probability that a randomly selected car along the same portion of the highway was a speeding sports car can be calculated as follows,

\begin{aligned}{\text{Probability}}&=0.52\times0.35\\&=0.182\\\end{aligned}

The probability that a randomly selected car along the same portion of the highway was a speeding sports car \boxed{0.182{\text{ or 18}}{\text{.2\%}}}.

This is a typo and vaguely phrased. However, the closest to a direct solution is to think of it as follows: 35% of the cars are speeding. Out of these, 52% of the cars are also speeding. Hence, the result of cars that are both speeding and speed cars is 0.52*0.35=0.182
