Is there a way to combine the graphic of a ListPlot to the graphic of a Plot? (I need to plot a graphic of a function on the graphic of a ListPlot)

    You can combine any graphics with the Show function like so:

    Show[myListPlot, myPlot]
    

    This generalizes to combining any number of plots at once: Show[p1, p2, p3, p4, ...] or Show[{p1,p2,p3,p4,...}]

    You can use Epilog as well if Show is not stacking the graphics in the correct order, but combining more than 2 graphics with Epilog will be unwieldy.

    From your second line, I think Epilog is what you are looking for. Here's an example:

    f[x_] := 1/Sqrt[2 Pi] Exp[-(x^2)/2];
    ListPlot[
     Table[
      {x, PDF[NormalDistribution[], x]}, {x, -4, 4, 0.1}
      ],
     Epilog -> First@Plot[f[x], {x, -4, 4}, PlotStyle -> Red]
     ]
    

    enter image description here

    Another way to do the same would be to use Show

    p1 = ListPlot[
       Table[
        {x, PDF[NormalDistribution[], x]}, {x, -4, 4, 0.1}
        ]
       ];
    p2 = Plot[f[x], {x, -4, 4}, PlotStyle -> Red];
    Show[p1,p2]
    

    On the other hand, if I was mistaken and you just wanted to combine them in the sense one next to the other, then you can use GraphicsRow or GraphicsColumn.

    FullGraphics@GraphicsRow[{p1, p2}]
