How do I detect if the mouse position is outside a panel and its children in WinForm

Point MousePos = MousePosition;
Point pnlPos = pnlPriceChoice.Location;
Size pnlSize = pnlPriceChoice.Size;

Console.WriteLine($"Mouse Pos: {MousePos.X}, {MousePos.Y} \n LowerBound: {pnlPos.X}, {pnlPos.Y} \n UpperBound: {pnlPos.X + pnlSize.Width}, {pnlPos.Y + pnlSize.Height}");

if (!(MousePos.X >= pnlPos.X && MousePos.X <= pnlPos.X + pnlSize.Width && MousePos.Y >= pnlPos.Y + pnlSize.Height && MousePos.Y <= pnlPos.Y))
{
    pnlPriceChoice.Visible = false;
}
