While there are still some on the table, a red ball has to be potted before one of the other coloured balls can be potted. Players must alternate the potting of a red and another colour. Once the reds are all potted the remaining colours must be potted in the following order: Yellow, Green, Brown, Blue, Pink and Black.
A snooker in pool can be deliberate (by your opponent) or accidental (by yourself). It is when the a straight line path from the cue ball to the object ball is blocked by another ball which may not be hit.
D. The semi-circle that adjoins the baulk line creates the D shape. The cue ball is placed there at the start of a frame and when it is returned to the table after being potted.
The white ball in Snooker is called the "Cue Ball".
That will depend on different things. It can be 4, 5, 6 or 7 points. For example, if they accidentally potted the black, it would be 7 points. If they intended to pot a red and potted the yellow, it would be 4 points.

There is only one white ball - the cue ball. It is the only ball which is not meant to be potted at any time.
Five points.
The black ball is put back on the table and the players try to pot it in order to win.
All of them could be, but it is rare to even see two being potted in a game. It is not to the advantage of a player to do so. In fact it is a disadvantage. After potting a red, the get to choose a colour to go for, and if they get it they can go for another red. However, if they pot more than one red in one shot, they still only get to go for one colour in the next shot before having to again try for a red.
In snooker, after potting all the reds on the table, you are required to pot Yellow, Green, Brown, Blue, Pink and finally Black in the mentioned sequence.
