Clear-cut cine-substitution would give a 1:1 ratio but additional steric and electronic factors come into play as well.

The 1,4- isomer is preferred over the 1,2- isomer due to steric hindrance.

Interestingly this is an example with extreme stereoselectivity due to the severe steric hindrance of an ethano-bridge.

Strict steric constraint exists around the pyrrolidine ring of cyanopyrrolidine-based inhibitors, with only hydrogen, fluoro, acetylene, nitrile, or methano substitution permitted. 2.

In addition, nucleophiles always attacks the secondary carbon of the oxirane ring because of stability of the intermidiate and steric hindrance.

Nevertheless, some reactions exhibit steric factors greater than unity: the harpoon reactions, which involve atoms that exchange electrons, producing ions.

The steric interaction between the pyrrolidine ring and the electrophilic reagent hinders the attack of the electrophile from the top face.
en.wikipedia.org
Formaldehyde reacts with water so readily because its substituents are very small- a purely steric effect.
en.wikipedia.org
By controlling the stoichiometry and steric properties of the alkoxide, such reactions can be arrested leading to metal-oxy-alkoxides, which usually are oligonuclear complexes.
en.wikipedia.org
As steric hindrance around the electrophilic center increases, as with isobutyl bromide, substitution is disfavored and elimination is the predominant reaction.
