Let $x_i,Y_{i}N(0,1).$ Say each random variable records how good the burgers $(x)$ or fries $(Y)$ are at a fast food restaurant. You've rank $1000$ restaurants $($wow$).$ In Python, you can simulate $1000$ points quality, meaning the combined quality of the burgers and fries must be greater than some threshold. Write this subset as $S=\{(x,Y)$:$x+Y>1\}.$ In Python, the set $S$ can be created as an array by writing $S=np.c_{-}[x,Y][np.$where$((x+Y)>1)[0]].$ Plot both the original scatter plot and your new scatter plot. Describe the relationship. Based on your recommendation, would your friends think good burgers cause bad fries?
