In the trigonal bipyramidal geometry, which position- axial or equatorial- do nonbonding electrons prefer? why?
I know its equatorial but I'm not exactly sure why

Lone pairs that are non-bonding occupy more space than atoms bonding electrons and they are less crowded when in the equatorial position. Whether it is AB4U, AB3U2, or AB2U3, the non-bonding pairs are equatorial because they are less crowded there. Most texts have decent diagrams that will let you visualize the arrangement.
It can be 1,2and 3
