Generate random numbers that add to 100

This is real work, not a feature someone invented — it comes from real job ads and real questions people asked. Below are four ready AI prompts: get it done, make it easy for the next person to say yes to, work out the right move when you are stuck, and stop it coming back.

The same task, four prompts

AExecute — do the immediate taskGenerate 5 random numbers that sum to exactly 100, ensuring they are all positive and distinct,…+
Generate 5 random numbers that sum to exactly 100, ensuring they are all positive and distinct, then display them.

I need a set of 7 random numbers that sum to 100, but they need to represent percentages for a budget allocation. Make sure they're all positive integers, and if any are too small to be meaningful (less than 2), re-distribute that value so the larger ones grow slightly, then show the final list.

The simulation just ran, and the random numbers for the component failure rates are all over the place.
The simulation just finished, and the random numbers representing component failure rates are making the reliability model unstable. I used a uniform distribution, but the results are too extreme. Dr. Evans will reject this if it doesn't show a more realistic spread. I can't tell if I should use a normal distribution with a specific variance or if there's a better way to constrain the randomness so the sum still makes sense. What's the best way to generate these random numbers to reflect realistic, stable failure rates for the 10 components, ensuring they sum to 1.0 but don't have wild outliers, and how do I explain this choice to Dr. Evans?

I keep struggling to get random numbers to behave realistically in my models.
I'm always losing time trying to generate random numbers that are both truly random and also meet specific real-world constraints, like summing to a fixed value or staying within a narrow range. My models often become unstable or unrealistic because of this. What habit should I change to consistently generate constrained random numbers that reflect physical reality without introducing bias?

Questions people actually ask

honest answers, no sign-up

Every task here was seen in the real world. Someone doing the job named it, a real job ad asked for it, or a lot of people asked about it online.

If nothing real showed a task, it is not on the page. That is the whole rule.

They are the same job approached four ways, because what you need depends on where you are.

Get it done today. Make it easy for the next person to say yes to. Work out the right move when you are stuck. Learn the pattern so the job stops coming back.

For most of these jobs it can carry the heavy thinking - draft it, sort it, check it, rehearse it with you.

It cannot sit in your chair, take the blame when a number is wrong, or notice what nobody wrote down. Let it do the first 80%. Keep the last 20% that is truly yours.

No. Copy any prompt and paste it into the AI you already use. No account, no score, no wall in the way.

Any of them. The prompts describe the work rather than naming a product, so they are not tied to one assistant.

That is also why they keep working when you switch.

Change it freely. Every prompt is a starting line, not a rule.

Put in your real numbers, your real names and your real deadline. The more you make it yours, the better the answer comes back.

The tasks come from real job ads, published job data and the questions people ask in public forums.

The steps come from MATLAB's own documentation, with practitioner sources for the traps the manual does not mention.

Push once. Ask it to sharpen the weakest part and to say what it assumed.

Most wrong answers come from a missing detail rather than a bad prompt - tell it the thing it could not know.
