The expected duration comes out to around 5 months.

Totally agree, that pessimistic estimate skews everything!

Wait, how can the pessimistic be a whole year? That seems off.

So it's definitely not just 4 months!

Expected duration is calculated using the formula (O + 4M + P) / 6.

If I remember correctly, the expected duration is calculated as (Optimistic + 4*Most Likely + Pessimistic) / 6, but I'm not confident about the numbers.

I feel like the pessimistic duration really skews the average, but I can't recall the exact calculation method.

I remember practicing a similar question, and I think you average the optimistic, pessimistic, and most likely durations somehow.

I think the three-point estimating technique uses a formula, but I'm not entirely sure how to apply it here.

Wait, I think the formula is (Optimistic + 4 x Most Likely + Pessimistic) / 6. Let me double-check that and work it out.

The most likely duration is 4 months, the optimistic is 2 months, and the pessimistic is 12 months. I'm pretty sure the expected duration is the average of these three values.

Hmm, I'm a bit unsure about the formula for calculating the expected duration here. Let me think this through step-by-step.

Okay, this looks like a classic three-point estimating problem. I think I can handle this one.

I've got this! The missing factor is definitely the material properties of the components. That makes perfect sense in the context of vibration-induced fatigue. I'm feeling good about this one.

This is a tricky one. I'm not entirely sure what the "except" part means, but I'll give it my best shot and try to eliminate the odd one out.

Hmm, I'm a bit confused by all the technical details in the images. I'll try to break it down step-by-step and see if I can figure out the correct answer.

I don't know, man. I'm just here for the free donuts. What's this about three-point estimating? Can I use that to estimate how many donuts I can eat in one sitting?

This is easy! The expected duration is the average of the three estimates. So, (2 + 4 + 12) / 3 = 6 months. Wait, that's not one of the options. I guess I'll just go with C - five months.

Hold on, isn't the three-point estimating technique supposed to give us a more accurate estimate? I'm going to have to do some calculations on this one. Hmm, I'll go with option D - twelve months. Better safe than sorry, right?

Okay, let's think this through. The most likely duration is four months, the optimistic duration is two months, and the pessimistic duration is one year. I'm going to go with option C - five months. That sounds about right.

Yes, five months makes sense based on the three-point estimating technique.

This is a trick question! The expected duration is clearly not two months, four months, or even twelve months. Whoever came up with this needs to go back to school.
