1. The problem statement, all variables and given/known data
A box of kiddimix contains 20 chocolates of which 8 are plain chocolates and 12 are milk chocolates. If 16 of the 20 have soft-centres, what can you say about how many plain chocolates there are with soft-centres?

2. Relevant equations
You can say there are 8/20 plain chocolates and 12/20 milk chocolates
16/20 are soft-centres
4/20 are non-soft centres.

3. The attempt at a solution
What can you say about how many plain chocolates there are with soft-centres?
Well you can for sure say there are 16/20 soft-centres but what can I say about the plain chocolates with soft-centres? Please help...

What is the fewest number of plain chocos with soft centers?

Is it 1?

If that's correct, then the other 15 with soft centers must be milk chocolate. Is that a problem?

Then it must be 4 plain soft chocolates with soft centres as there are 12 milk chocolates. Still not very clear as why though

It would be difficult for 15 out of 12 milk chocolates to have soft centers, would it not?
