What is the sample space for an experiment that consists of drawing two balls, one
at a time without replacement out of a bag that contains 3 red balls, 4 white balls,
and 6 green balls?
S = \{rr, rw, rg, wg, ww, gg\}
S = \{rrr, www, ggg, rwg, rrg, rrw, ggw, ggr, wwr, wwg
S = \{r, r, r, g, g, g, g, g, g, w, w, w, w\}
S = \{rr, rw, wr, rg, gr, wg, gw, ww, gg\}
