History

Saved a checkpoint:
Renamed 'name' to 'pname' to avoid a conflict with the marking algorithm.

Saved a checkpoint:
Split the first part, about basketball, into a separate question.
Added random names.
Changed the randomisation of the probabilities so that everyone is pulled from the same distribution (apart from the missing person, who accumulates the error when the probablities for the others are rounded off)

This is a nice question, but I have some comments.
- While the parts are very clear, I feel like it looks a bit daunting that the statement is almost as long as the whole question. I would personally put some of the statement in the advice (so the first time they do the question you test them on this and the next time they redo it, they'll know all this helpful information) but it is up to you.
- Part a) is a good simple question. Just a tiny unnecessary comment, your Hoop variable has a description of "Denominator for probability that your car runs out of fuel before you get to Leeds", I assume that this was how you first wrote the question and changed it to a different situation afterwards forgetting you have to fix your variable description.
- Also, you used random(5..9 #1) in your variable, a step size of 1 is the preset setting so the #1 is unnecessary there. It isn't wrong at all and you should keep it there and maybe you realise this, I just thought to let you know in case you need to use random integers in future so the job is a bit easier for you.
- Also, when Hoop = 7, Numbas does not accept the decimal form of the answer my calculator gives. I don't know if this is a big deal, but maybe some students would try to put decimal forms instead of fractions in. Maybe you could say in the question put your answer as a fraction?
- Part b) - I am not 100% convinced about pass the parcel being the right game for this question, but it is not a big deal.
- I feel like it would be better to swap parts i) and ii), because to get the answer to part i), you already had to calculate the answer to part ii). Maybe the order is like it is right now because you were aiming to test whether they realise this so if that is the case, that's fine.
- The advice for part b)ii) is maybe a bit too complicated considering how simple it is in reality, especially when one of the methods you use is the same as in part a). I think putting the second method first would maybe be better.
- If you swap parts i) and ii): in advice for the new part ii) (calculate the probability of Dexter winning), you could use P(E) = 1 - P(E'), a slightly different turn on the equation for complementary probabilities. This would make part b)ii) a bit different from part a).
- You use latex for $P(.)$ which is fine but I would personally use $\mathrm{P}(.)$ as it looks nicer in my opinion. This is coded as
$\mathrm{P}(.)$.It is a good question as it is right now. This is all just my personal opinion of what you could change so it is up to you to decide which things are better now and which things would be better changed.

For each combination of answer and choice, specify the number of marks to add or subtract when the student picks it.
For each combination of answer and choice, write 1 if the student should tick it, or 0 if they should leave it unticked.
Test that the marking algorithm works
Check that the marking algorithm works with different sets of variables and student answers using the interface below.
Create unit tests to save expected results and to document how the algorithm should work.
There's an error which means the marking algorithm can't run:
This is an extension type part. There is no expected answer, and it's assumed that the marking depends on interactions within the part's prompt.
You can test this part's marking algorithm by interacting with the rendering of the part's prompt below.

When you need to change the way this part works beyond the available options, you can write JavaScript code to be executed at the times described below.
To account for errors made by the student in earlier calculations, replace question variables with answers to earlier parts.
In order to create a variable replacement, you must define at least one variable and one other part.
| Variable | Answer to use | Must be answered? | |

The variable replacements you've chosen will cause the following variables to be regenerated each time the student submits an answer to this part:
These variables have some random elements, which means they're not guaranteed to have the same value each time the student submits an answer. You should define new variables to store the random elements, so that they remain the same each time this part is marked.
This part can't be reached by the student.
