Triangular Angle II

A release-checked easy problem for training Uniform, Geometric Probability.

Question

A right triangle is being formed with leg lengths $X$ and $Y$, where $X,Y \sim \unif{0}{1}$ IID. Let $\theta$ be the measure of the (random) angle that is opposite of side $Y$. Find $\prob{\theta > \dfrac{\pi}{3}}$. If necessary, round to the nearest thousandth.
