An automobile manufacturer produces 77% of its cars at plant A. If 3% of the cars manufactured at plant A have defective emissions control devices, what is the probability that one of this manufacturer's cars was manufactured at plant A and has a defective emissions control device?

Probability (Type an integer or decimal):

Answer :

Final answer:

The probability that a car from the manufacturer's plant A has a defective emissions control device is 0.0231.

Explanation:

To find the probability that a car from the manufacturer's plant A has a defective emissions control device, we need to multiply the probability that a car was manufactured at plant A by the probability that it has a defective emissions control device.

The manufacturer produces 77% of its cars at plant A, so the probability that a car was manufactured at plant A is 0.77.

3% of the cars manufactured at plant A have defective emissions control devices, so the probability that a car manufactured at plant A has a defective emissions control device is 0.03.

To find the probability that a car was manufactured at plant A and has a defective emissions control device, we multiply these two probabilities:

0.77 * 0.03 = 0.0231
