SDCAR2010【逻辑入门】（八）Assumptions

无敌西红柿炒蛋

Hi,Sdcar!
For Q 1,the premise is "33 percent of all vehicles ticketed for exceeding the speed limit were equipped with them".  And  the main conclusion is "drivers who equip their vehicles with radar detectors are more likely to exceed the speed limit regularly than are drivers who do not."
If my judgement is correct, and what's the gap between the premise and the conclusion. In view,through the condition and the premise ,we can logically deduce the conclusion.
Could you explain it explicitly ?This question confuse me a lot.
