Final answer:
The risk associated with a Blood Alcohol Concentration (BAC) of 0.10 percent is generally higher than at the legal intoxication limit of 0.08 percent; however, the question does not provide sufficient context or data to determine the exact increase in risk.
Step-by-step explanation:
The question refers to the increased risk associated with a Blood Alcohol Concentration (BAC) of 0.10 percent. It is well-documented that higher BAC levels correlate with greater impairment and risk of accidents, health events, and legal consequences. At a BAC of 0.08%, individuals are legally considered intoxicated, and this level is enough to affect judgement and motor skills significantly. The risk, although not specified in the question, generally increases as the BAC rises. At 0.10%, a person's risk for accidents and health effects is greater than at 0.08%, but the exact multiplier for this increased risk would typically be found in a study or statistical data on traffic accidents or alcohol-related health events.
