Sam has 12 shirts: 3 red shirts, 2 blue shirts, and the remaining shirts are green. Sam also has 3 pairs of black trousers, 3 pairs of grey trousers, and 2 pairs of brown trousers. If Sam chooses one shirt and then one pair of trousers at random, what is the probability that Sam chooses a green shirt and a pair of black trousers? (3 d.p.)
