My Biscuit Teddy contains biscuits in this ratio:
1x Bourbons @ 12 per packet
1x Malted Milk @ 24 per packet
1x Digestive @ 27 per packet
2x Nice @ 26 per packet

What is the chance of me getting 3 Nice biscuits ((my favourite) assuming a random grabbage factor)

:scratch: total number of biskits is

12
24
27 and
52
equals 125 :scratch:

so using Desmond's equation of coincidental options.... :scratch::unsure:

put the Bourbons, malted milks in the teddy, give me the digestives, and you can layer your nice biscuits on the top of the Bourbons and malted milks.

1st pick is 52 in 115.
2nd is 51 in 114.
3rd is 50 in 113.
Multiply to get the answer?
Approx 1 in 11. Caveat: Decades since i studied "prob" at school.
or

Zero, the bl##%y kids ate the lot!


Edit: someone can't add up, hope it's not me

If you start with 125 biscuits, and eat 30 of them, what do you end up with?

Really bad tummy ache!

(OK, I admit it, I stole that from one of that pantos I was working on the other week...
