assembly - x86 Assembly - Which value is in ebx?

Question

mov eax, 47
push eax
mov eax, 11
push eax
pop ebx

Which value is located in ebx?

I'm not really sure what should be in ebx, probably a random value? On the stack, there should be (from high to low) 47, 11 but we know nothing about ebx. Is this just a trick question?
