I’m pretty confident that the answer is around 0.909, but I can't remember if I should round it to six decimal places or not.

I feel like I should start with some trial values around 0.9 and see how they fit into the equation.

I'm not 100% sure on this one. The wording of the question is a bit tricky. I think I'll go with option A just to be safe, but I'm not entirely certain that's the correct answer.
