Hello. I have the error displayed in the title. I get this error when I choose "solve for p" when hovering over the following expression:
"
limit(sum(p^k*(1-p)^(x-k)*log2(factorial(x)/(factorial(k)*factorial(x-k))), k = 0 .. x), x = infinity)
"

Did I type in my expression badly or is it just not solvable?
