Question: A security update reduces the vulnerability of a system by 75%. If the initial vulnerability score was 80, what is the new score?

Options:

Correct Answer: 20

Solution:

80 - (80 * 0.75) = 20.

A security update reduces the vulnerability of a system by 75%. If the initial vulnerability score was 80, what is the new score?

A security update reduces the vulnerability of a system by 75%. If the initial vulnerability score was 80, what is the new score?

Step 1: Identify the initial vulnerability score, which is 80.
Step 2: Determine the percentage reduction in vulnerability, which is 75%.
Step 3: Convert the percentage reduction into a decimal by dividing by 100. So, 75% becomes 0.75.
Step 4: Calculate the amount of vulnerability reduced by multiplying the initial score by the decimal. This is 80 * 0.75.
Step 5: Perform the multiplication: 80 * 0.75 = 60.
Step 6: Subtract the reduced amount from the initial score to find the new score. This is 80 - 60.
Step 7: Perform the subtraction: 80 - 60 = 20.
Step 8: The new vulnerability score is 20.
