To find the number of plain glazed doughnuts, first calculate the total number of doughnuts with icing.
The number of chocolate icing doughnuts is 3/8 * 12 dozen = 3/8 * 12 * 12 = 36 doughnuts.
The number of white icing with sprinkles doughnuts is 1/4 * 12 dozen = 1/4 * 12 * 12 = 36 doughnuts.
The number of pink icing doughnuts is 1/6 * 12 dozen = 1/6 * 12 * 12 = 24 doughnuts.
Therefore, the total number of doughnuts with icing is 36 + 36 + 24 = 96 doughnuts.
The total number of doughnuts is 12 dozen * 12 = 144 doughnuts.
Thus, the number of plain glazed doughnuts is 144 - 96 = 48 doughnuts. Answer: \boxed{48}.
