Hannah’s Sweets

I have just done my Maths DCSE (Dog Certificate of Secondary Education). Blinking Nora, it woz difficult. One of the questions woz nearly impossible to answer.

ROVER’S BISCUITS

Rover has a number of biscuits, six black kennel-shaped biscuits and an unidentified number of orange fish-shaped ones. Overall he has ‘N’ biscuits.

Rover eats one of the biscuits – it’s black. He then eats another biscuit, this is also black.

The probability of him eating these two black biscuits is a third.

How many biscuits will be left?

I sat for a long time pondering this question. Finally I used the following formula to work it out:

N = 6 (black) + N-6 (orange) – 1 x black = N-6-1 (black) = 0

Therefore there are zero biscuits left.

Wen I got home I asked Ian to carry out a practical experiment to prove this and he did a video of me…
