The probability of finding love

I bought a box of gingerbread letters L-O-V-E

We picked letters out at random and counted how many turns it took to find 'LOVE'. 
First we said the letters had to be chosen in the right order. 
Then they could be chosen in any order, as long as we ended up with LOVE.
There were 4 L biscuits, 4 O biscuits, 5 V biscuits and 5 E biscuits.



The probability of finding 'LOVE' and selecting the letters in the right order, on average it would take 200 attempts to find 'LOVE'.


But if you're not as picky and happy to find 'LOVE' in any order as long as it's love, then the probability is 1 in 7.
And then we tried it out and sure enough in seven attempts we found LOVE once...
Rosie was the only one to find LOVE!

and at the end of the maths lesson, we could decorate and eat LOVE!

For online practice of probability, we used:
