Dear Monique,
The answer should be choice A: US$-38,000.
You need to calculate the EMV of Project A and B, and select the highest gain (more +) or the lowest loss (less -) between EMV of Project A and B.
EMV of Project A = -650,000 (cost) + 56% x 1,800,000 (success) - 44% x 900,000 (failure) = -38,000
EMV of Project B = -467,000 (cost) + 67% x 950,000 (success) - 33% x 670,000 (failure) = -51,000
Since -38,000 is bigger than -51,000, this is the answer.
