Could somebody help me with this Chemistry question?

If a solution of CaF2 has [Ca++] = 3.1 x 10^-4 and [F-] = 1.5 x 10^-3, and if PbI2 has Ksp = 3.9 x 10^-11, will a precipitate form in the solution?

No, I don't think there's anything missing, I saw this in my friend's textbook the other day, and it has been picking at me ever since...

I guess I assumed that maybe the two compounds had something in common that I didn't notice, and perhaps that was the key to solving this...

is missing the solvent, because Calcium fluoride cannot react by itself

If you can solve this, you can change lead into gold. Is something missing?
