Ok - am I missing something here? Apparently loads of GCSE students are complaining about this question:
There are 'n' sweets in a bag.
6 of the sweets are orange.
The rest are yellow.
Hannah takes one sweet at random.
She eats the sweet.
She takes another sweet at random.
She eats the sweet.
The probability that Hannah eats two orange sweets is 1/3
a) Show that n(squared) - n - 90 = 0
Erm surely this is REALLY easy? - actually no............... no it isnt.
