In risk management, to calculate the contingency budget for risks, we use the Expected Monetary Value (EMV) formula: EMV=Probability of Risk×Impact of Risk\text{EMV} = \text{Probability of Risk} \times \text{Impact of Risk}EMV=Probability of Risk×Impact of Risk

For Risk A:

Probability: 40% or 0.40

Impact: US$100,000\text{EMV of Risk A} = 0.40 \times 100,000 = US$40,000

For Risk B:

Probability: 60% or 0.60

Impact: US$20,000\text{EMV of Risk B} = 0.60 \times 20,000 = US$12,000

Total contingency budget = EMV of Risk A + EMV of Risk B

40,000 + 12,000 = US$52,000

Thus, the total contingency budget required for both risks is US$52,000. This approach follows PMI’s risk management guidelines, specifically under the " Quantitative Risk Analysis " process. This process focuses on determining numerical probabilities and monetary impacts to compute the expected financial impact of identified risks​​.
