PK0-005 Tools and Documentation Practice Question
A project manager is reviewing the risk register and sees that a high-impact risk has a probability of 0.3 and an impact of $50,000. The team implements a response that reduces the probability to 0.1 and the impact remains $50,000. The response cost is $5,000. What is the net expected monetary value (EMV) of implementing the response?
⚠ Common exam trap
PK0-005 often tests whether candidates stop at the gross risk reduction ($10,000) and forget to subtract the response cost, or confuse the original EMV ($15,000) with the net benefit — the trap is a multi-step calculation where each distractor corresponds to a partial answer.

Correct answer & explanation
✓
$5,000
The original EMV is 0.3 × $50,000 = $15,000. After the response, the EMV is 0.1 × $50,000 = $5,000, so the risk reduction saves $15,000 − $5,000 = $10,000. Subtracting the $5,000 response cost gives a net EMV benefit of $5,000, which is the correct answer.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
-$5,000
Why it's wrong here
A negative value would indicate the response is not cost-effective.
- ✗
$15,000
Why it's wrong here
This is the original EMV, not the net benefit.
- ✓
$5,000
Why this is correct
Reducing probability from 0.3 to 0.1 cuts expected loss from $15,000 to $5,000, saving $10,000. Subtracting the $5,000 response cost leaves a net EMV benefit of $5,000, satisfying the stem's requirement to quantify the response's net value.
- ✗
$10,000
Why it's wrong here
This is the reduction in EMV before subtracting cost.
