Final answer:
True, in a comparative negligence system, a contributorily negligent plaintiff can recover a portion of their damages reduced by their fault percentage, which is similar to how coinsurance works in insurance policies.
Step-by-step explanation:
True, under a comparative negligence system, a contributorily negligent plaintiff (denoted as π) is indeed allowed to recover a percentage of her damages. The damages the plaintiff can recover are indeed reduced according to her proportionate share of the fault. This means if a plaintiff is found to be partially at fault for the incident that led to their damages, their recovery would be diminished in proportion to their own negligence. This is akin to the concept of coinsurance in insurance policies, where the policyholder pays a certain percentage of a loss, and the insurance company pays the remaining cost.
