Let $Q$ be a point in coordinate space, where all the coordinates of $Q$ are positive. The line between the origin and $Q$ is drawn. The angle between this line and the $x$-, $y$-, and $z$-axis are $\alpha,$ $\beta,$ and $\gamma,$ respectively. If $\cos \alpha = \frac{2}{5}$ and $\cos \beta = \frac{3}{5},$ then determine $\cos \gamma.$
