Traffic data revealed that 35 percent of automobiles traveling along a portion of an interstate highway were exceeding the legal

speed limit. using highway cameras and license plate registrations, it was also determined that 52 percent of sports cars were also speeding along the same portion of the highway. what is the probability that a randomly selected car along the same portion of the highway was a speeding sports car?

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

Write the explicit formula for the geometric sequence 2, 8, 32, 128
Alja [10]
The first term, a, is 2.  The common ratio, r, is 4.  Thus,

a_(n+1) = 2(4)^(n).

Check:  What's the first term?  Let n=1.  Then we get 2(4)^1, or 8.  Is that correct?  No.

Try this instead:

a_(n) = a_0*4^(n-1).  Is this correct?    Seeking the first term (n=1), does this formula produce 2?      2*4^0 = 2*1 = 2.  YES.

The desired explicit formula is   a_(n) = a_0*4^(n-1), where n begins at 1.

A. The number of fabric-pattern-color combinations is 4 * 13 * 9 = 468

B. P(1st choice) = no of novels / total books = 3/6 = 1/2
    P(2nd choice) = no of remaining novels/ total remaining books = 2/5
    P(both novels) = 1/2 * 2/5 = 1/5          (without replacement assumed)

C. P(1st choice) = no of biographies / total books = 2/6 = 1/3
    P(2nd choice) = no of remaining biographies/ total remaining books =        1/5
    P(both biographies) = 1/3 * 1/5 = 1/15          (without replacement                assumed)

D. P(1st choice) = no of history books / total books = 1/6
    P(2nd choice) = no of novels/ total remaining books = 3/5
    P(a history, then a novel) = 1/6 * 3/5 = 1/10          (without replacement assumed)
