Can't plot a function

Hey guys, I'm trying to plot this function into Sage and it does not work for some reason.

g(x) = binomial(3,x)*binomial(3,2-x) / binomial(6,2)

plot(g(x), (x,0,2))

Nothing shows up.

The command plot samples 200 points in the specified interval.

For the combinatorial function in the question, only integer values matter.

The corresponding plotting function is list_plot.

sage: g = lambda x: binomial(3, x) * binomial(3, 2 - x) / binomial(6, 2)
sage: glist = [g(x) for x in range(3)]
sage: gplot = list_plot(glist, ymin=0, size=30)
sage: gplot.show()
