In general, points in a convex hull can be expressed as a convex combination in more than one way. Illustrate this by considering the convex hull $cx\{w_1,w_2,w_3,w_4\}$ where $w_1=(0,0),w_2=(1,0),w_3=(1,1)$ and $w_4=(0,1).$ Give two explicit and distinct convex combinations for a suitable point of your choice in this convex hull. $($Hint: draw a diagram of the convex hull, and consider diagonal line segments.$)$
