because your working out is sorta garbage, they gave 1/4 because you had the correct answer and 0 for your working out. you can’t say 1.33 = -1.33 = 91.78% (or whatever it is you wrote), your equating a bunch of numbers together which makes no sense
1.3303 = ~~~ 1.33 = 90.82%

Your working out is fairly poor, but I can follow your solution quite fine.

Let's go through the marking criteria;

Calculates the correct z-value. While you did not notate what the z-value is, it is there; but some markers would argue you didn't actually say what the z-value is. Personally I would have given the mark but "technically" it's a bit dubious.
Finds the correct probability from the table; you notated the stem of the question to show this. I'd say this is valid, apart from writing 1.3=90.82%, which is an incorrect mathematical statement. Could have been set out better though.
Finds the correct proportion of the group of koalas. Again, you have this written down, but the setting out is very bad. 100=9.18% is an incorrect mathematical statement.
Provides correct solution; you have the answer, and the calculation from the proportion. I think you got this.

If I was marking harshly I would have given this a 2, one for proportion->answer and one for z-score->proportion less than. Your solution cannot be followed in a step by step order to the answer without knowing the steps you are doing. Markers give marks for mathematical reasoning and demonstrating mathematical ability; just writing down the numbers can be insufficient - that's what I think happened here.

While I'm interpolating your steps, the marker doesn't have the liberty to do so. I'd say the marker refused to "fill in the gaps" in the explanations in your answer. the only logical correct calculations in the answer that is relevant are the 400*9.18% and the z-score calculation, which doesn't fit cleanly into the marking criteria. While harsh, I do see the argument that that could be equivalent merit to 1/4...
lol i know this is from a while ago, but he gave the correct answer right? don’t you get full marks for correct answer regardless of working out?

usually correct answer is only one part of the marking scheme

ie no you won’t get full marks just for the answer in most large-mark questions
oh i see. maybe my school does it differently because our marking criteria is like this: e.g 3 mark question. 3 marks for correct answer. 2 marks for significant progress towards answer. 1 mark for any relevant information. is this completely different to how they do it in the hsc?

i tell this to all the students i tutor about once a lesson: the people that write the exam already know what the answer is, they just want to know that you know how to get there!

ahh okay that makes sense. but in that guys example he did do working out it was just a tiny bit unclear right? coupled with the right answer, should that not still get full marks?
a lot of his working was also just wrong and weird, like they were equating numbers that aren’t equal and stuff like that. hsc questions ask for a full correct solution not just a correct value. definitely harsh marking but not unreasonable

Guys im currnently doign trials & HSC year 2024 give all your tips, schedule everything pls
at this point, spam past papers to find things you don’t know well then review the basics of those things in the textbook and finally, go through the syllabus and be able to answer all the points should they have been asked of you as questions, if you can’t go back to past papers! always timed conditions as well
