Answer:

Option C - 0.0036

Step-by-step explanation:

Given : The probability that a new spark plug is defective is 0.06. You need two new spark plugs.

To find : What is the probability that both spark plugs you buy are defective?

Solution :

Probability of one spark plug being defective is 0.06

We have to find for two defective spark plugs.

This situation is a compound event in which there is more than one possible outcome.

So, The Probability of two spark plug being defective is

[tex]P=0.06\times 0.06[/tex]

[tex]P=0.0036[/tex]

Therefore, The Probability of two spark plug being defective is 0.0036.

So, Option C is correct.
