It just meant ur chances of getting a preferred coloured shirt.
i.e. If you want to pick a black shirt, it would be no. of black shirts divided by total number of shirts. In this case, the probabiliy to get the first black shirt is 8/16. The second would be 7/15. Hence, the total probability would be 8/16 × 7/15 = 7/30. You can try the rest on your own first :)
