Golf balls such as Titleist Nike and Callaway have 12 in a standard pack, each pack being made of 4 sleeves of 3 balls. Some other manufacturers make packs of 15 and 18.
Table tennis balls come in a variety of package sizes from 4 to 144. They also come in a variety of colors.

Judging by most ninety nine cents stores i've seen them in, eight to ten table tennis balls usually come in a pack. I've also bought a few packs that have contained around ten balls.
