Alewis structure is a two-dimensional representation of a molecule that does not necessarily show what shape that molecule would take in three dimensions. from the given lewis structure and what you know about vsepr theory, identify the shape of the molecule. a molecule with atom y single bonded with 2 x substituents. the y atom has one lone pair. t-shaped trigonal pyramidal trigonal planar octahedral tetrahedral square pyramidal see-saw linear square planar trigonal bipyramidal bent

Trigonal Pyramidal

Explanation:

The three electron pairs arrange themselves in this manner because of unequal repulsion between lone pairs and bonding pairs. according to VSEPR theory, the presence of three electron pairs leads to a trigonal planar arrangement. However, factors such as possession of a lone pair may lead to a different arrangement of electron pairs in space.  Repulsion between lone pairs and bond pairs often lead to a bent or angular molecule. If there were no lone pairs and only two substituents present in this molecule, the molecule will be linear, that will correspond to the presence of only two electron pairs.

It would make sense that the 10 green marbles has the best chance of getting picked.  Since you didn't provide any information on the experimental probability, then I can only answer the theoretical one.
