Gaussian contours. Roughly sketch the shapes of the following Gaussians N$(\backslash$mu $,\backslash$Sigma $).$ You only need to show a representative contour line which is qualitatively accurate $($has approximately the right orientation, for instance$)\mathrm{.}090($a$)\backslash$mu $=0$ and$\backslash$Sigma $=01$

$010\mathrm{.}75($b$)\backslash$mu $=0$ and$\backslash$Sigma $=0\mathrm{.}751$
