# Looking for anyone that suffered Hannah's Sweets? Edexcel Maths watch

1. I feel like we all bonded over that questions.
Anyway, i got a B in that exam (somehow) but my school are saying (to everyone) if you didn't get an A* youre retaking. In november i got another B (1 mark off an A) .
But the school have started teaching us the IGCSE for some reason and they said they aren't sure whether to take Edexcel GCSE or IGCSE. I am really struggling with the new stimulus as it is a lot of new stuff. I spoke with hte head of maths but she remained indecisive. I don't know what is happening can someone please explain?
2. I didn't know if you wanted an answer but I looked up " Hannah's Sweets Problem" and a lot of people struggled on it so: When Hannah takes her first sweet out of the bag, there is a 6/n chance it will be orange because there are 6 orange ones and an n amount of sweets. When Hannah then takes her second sweet out of the bag, there is a 5/(n-1) chance it will be orange. That’s because there are only 5 orange sweets left out of a total of n - 1 sweets. The chance of getting two orange sweets in a row is the first probability multiplied by the second one [Following so far?]. Which is 6/n x 5/n–1. The question tells us that the chance of Hannah getting two orange sweets is 1/3.So: 6/n x 5/n–1 = 1/3
All we need to do now is rearrange this equation.(6x5)/n(n-1) = 30/(n2 – n) = 1/3
Or 90/(n2 – n) = 1
So (n2 – n) = 90
Therefore: n2 – n – 90 = 0

Only your head of maths can explain what your school will decide to do. If they don't know, how could anyone else?

English state schools have had the choice to enter candidates for GCSE or IGCSE (also described as Level 2 Certificate), they are considered equivalent. Independent schools can enter for whatever they like. The igcse has a bit less focus on problem solving (something that is increasing in the new maths GCSE) and more focus on "maths" that includes a few new topics. It also permits you to use a calculator for both papers. Your teachers seem undecided about whether you have a better chance of improving your grade with yet another GCSE resit or by switching to igcse. Why they think everyone should be getting an A* is unclear.
