For P(0), isn't it supposed to be 5/12 * 6/10.
Coz there were 3 chocolates in Ahmad's bag, so the remainder is 6.

Dude.. but a toffee is getting added as well..! there were 4 toffees 3 choco and 2 Boiled.. but a toffee is getting added or the total will be 6/9 according to what you're saying since 3 choco and 6 remaining that's 9 total. .. which brings it to 5 toffees 3 choco and 2 boiled...

Ahh yeah.. I knew I had done something wrong in that question. But I got the value for P(2) as 4.75
Anways, that's the only question (so far) that I have messed up in..

That's Awesome! you'd get 3 in that question too.. 1 method mark will be lost and 1 accuracy mark. I messed up one part in permutation too :( Because I misread the question and took total chosen as 15 .. in the one where we had to find ways to do 12.

so i will lose 2 marks or gain 2 marks?
i think i should loose around 2 marks only -_- on the whole

If you drew the Tree Diagram incorrectly. AND TOOK all the values from there .. then you should be fine.. but if you didn't drew the tree diagram then I don't know :\

I would say 3 marks. all the accuracy ones..

A star

Honestly the last question wasn't clear IMO.. i mean they said they take out 2 toffees.. but they weren't clear whether they take out two toffees from sarah and add to Ahmed or take one toffee from sarah, put it in ahmed and then take one from ahmed :\
