a. If districts were drawn randomly, the most likely distribution of House seats would roughly align with the percentage of party affiliations in the population. In this case, with 60% Republican and 40% Democrat, we would expect approximately 6 Republican representatives and 4 Democrat representatives.
b. If districts could be drawn without restriction (unlimited gerrymandering), the maximum and minimum number of Republican representatives sent to Congress would depend on how the districts are drawn. It is difficult to determine an exact number, but gerrymandering could potentially result in a higher number of Republican representatives than the expected 6, or even a lower number if the districts are drawn strategically to favor the Democrats.
