I am trying to replicate the Parrondo paradox which can be found for example here books.google.co.uk/books  and

Why does the binary entropy function have the form   H := -p*log(p)-(1-p)*log(1-p);
Why does not the maximum occur when H=1 and p=0.5 ?

H := -p*log(p)-(1-p)*log(1-p);
plot(H, p = 0 .. 1);

How can i delay the evaluation in add. I want add to return

add( i, i=1..10)

                                    1+2+3+4+5+6+7+8+9+10

Now it returns

add(i, i=1..10)
