#EdexcelMaths is a Twitter hashtag associated with various jokes and complaints regarding a perplexing statistics problem known as “Hannah’s sweets" which appeared in the United Kingdom’s General Certificate of Secondary Education (GCSE) Math exam distributed by the Edexcel exam board in June 2015.


On June 4th, 2015, Twitter user @bethdedwards_[3] posted a tweet in anticipation of taking the GCSE Math exam[1] later that morning, including an image macro of an elderly man talking to a doctor in a hospital bed accompanied by the hashtag #EdexcelMaths (shown below).

The exam included a math problem for determining the probability of taking two orange sweets from a bag, which was subsequently referred to as "Hannah's sweets" (shown below).

19 There are n sweets in a bag. 6 of the sweets are orange. The rest of the sweets are yellow. Hannah takes at random a sweet from the bag. She eats the sweet. Hannah then takes at random another sweet from the bag. She eats the sweet. The probability that Hannah eats two orange sweets is (a) Show that r-n-90=0


That morning, many United Kingdom-based students began complaining about the exam's difficulty and mocking the Hannah's sweets question on Twitter, accompanied by the hashtag #EdexcelMaths.[4]

The same day, a petition requesting that Edexel "reduce grade boundaries significantly" was submitted to Change.org[2] (shown below, left). On June 5th, Twitter user @themaine4_ever[5] posted a photograph of the "Hannah's sweets" solution written on a piece of notebook paper (shown below, right).

This isn't due to lack of effort but due to the extent of sheer difficulty in the paper. Fair enough, the first half was alright however there on it goes quite downhill proving impossible even for the most able students. On a personal note, this is affecting our ability to focus on our other exams due to the thought of how atrociously the Maths paper went Street address Zip code I'm signing because (optional) C) f Share with Facebook friends Sign Maya ★ ☆40 @themaine4一ever Follow #EdexcelMaths To all the idiots crying over the Hannah's sweets question, maybe y'all should have stopped panicking Lo RETWEETS FAVORITES 85

The probability you pull out an orange sweet is 6/n. After she pulls the first sweet there are only 5 orange ones left and n-1 in total. The probability of 2 independent events being occurring is the product so the probability she gets 2 orange sweets is (6/n)*(5/n-1) and we are told it equals 1/3. Should of learned that basic fact if not figure it out yourself with an example. All the question is asking you to do is to rearrange the equation so it looks like n^2-n-90 = 0. Pathetic.
