Here is a Maths question that was in the GCSE in Britain this year. I did a different paper this year instead of the regular GCSE but I still had a go at this question. I found it absolutely fine but loads of people found it hard and some even complained to the Exam Board!
Do you find it hard?
1: The number of sweets in a bag is n. Six of those sweets are orange flavoured. Hannah takes a sweet at random from the bag and eats it. She then takes another sweet from that bag and eats it. The probability that she took and ate two orange flavoured sweets is ⅓.
a: show that n² − n − 90 = 0
b: solve n² − n −90 = 0
