The impossible maths question -- NOT!

Is its just me or was the so called impossible maths GCSE question not that hard? The maths involved were straight forward, just simple probability followed by plugging the numbers into the formula for solving a quadratic equation, the question was really about recognising what the problem was and breaking it down into simple simple steps. I was far from brilliant at maths and that was 40 plus years ago but it would only took me 2 minutes after I had read the problem through twice.

Well, I broke both my arms on the Sunday last day of the summer holiday before the 4th year...

So, I was told not do PE and instead did an extra maths lesson! I loved it, was really good at it and got an A for maths and physics...

Now I cant remember a thing about it!!

There are n sweets in a bag. Six of the sweets are orange. The rest of the sweets are yellow.

Hannah takes 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 1/3. Show that nē-n-90=0


Simple really and I am old enough to have done 'O' levels, then again maybe that is the point.
