In the Maths GCSE, there were a couple of questions which I got wrong, but the working may or may not be good enough for me to gain marks. Is anyone willing to have guess as to how many marks I achieved for each question? (you can only help out on a few or one question if you want) Please put my mind at rest. Thanks!
-> Questions asking about events
Something similar to:
"why is daisy wrong? (lists 2 independent events) 12/23 and 2/23 chance respectively of happening. Daisy does 12+2 = 14, so 14/23 chance of both happening"
For a question like this in Paper 2, I said "because the events are independent"
For a question like this in paper 3 I said "because you have to multiply the probabilities, not add them"
Will only one get the mark, will both, or none at all?
->Some of my ****** in Paper 1 (including digital working out! woo!):
-> An inequalities question on Paper 3: worth 4 marks. "Give the 3 equations which satisfy these inequalities".
I give 3 equations, but instead of "less than
or equal to" I simply put "less than". All 3 equations had the numbers correct - only that my signs did not include the 'or equal to'. Would that be no marks, or 1 mark?
I understand that this is a demanding topic and I might not get any replies. But it's worth a shot to see if I really have a chance at a Grade 9 or not.
