It is trigonal pyramidal and #"sp"^3# hybridized.

Explanation:

The Lewis structure of #"CH"_3:^"-"# is

Lewis structure

The carbanion has three bonding pairs and one lone pair.

Thus, VSEPR theory predicts a tetrahedral electron geometry and a trigonal planar electron geometry.

Geometry

A tetrahedral electron geometry corresponds to #"sp"^3# hybridization.
