Rather than use Triangular Distribution while doing Three Point Estimation you choose to use Beta Distribution.Based on your analysis and understanding you are confident that the project would be completed with a total cost of 108,000 $.You also estimate that a best case estimate would be 90000 $ while a worst case scenario would result in the costs incurred to shoot up to 138000 USD. What would the Three point Cost estimate be using Beta Distribution?

Correct Answer : B
The correct answer is B.The question states we should use Three point estimate using Beta distribution. The formula for this estimation technique is 4a + b + c / 6 where a = Most Likely estimate , b = Estimate based on Best case scenario and c = Estimate based on Worst case scenario. So the Three point estimate using Beta distribution is (4 *108000) + 90000 + 138000 / 6 = 660000/6 = 110000 $
