You could use the option *Epilog* and the graphic function *Point* as in

ListPlot[{firstList, secondList, thirdList},
  Joined -> {True, True, True, False}, Epilog -> Point[aPoint]]

For instance,

ListPlot[Table[{k,
    PDF[BinomialDistribution[50, p], k]}, {p, {0.3, 0.5, 0.8}}, {k, 0,
    50}], Filling -> Axis,
  Epilog -> {PointSize[Large], Pink, Point[{20, 0.10}]}]
