ok i'd appreciate it if someone could give me the answer to this one problem and tell me how its solved so i can do the rest on my own....

gwen has 4 blue pens, 8 black pens, 2 green pens and 3 red pens in her drawer. she takes out two pens without replacing the first one. find the probabiliyy of her pulling out a green, then blue pen.

that probability would be 2/17 * 4/16
=1/34 ..... (2 greens from a total of 17, then 4 possible blues from the remaining 16)
