Drivers between the ages of 18 and 64 in different countries were asked if they had driven while talking on their cell phones within the 30 days before they took the survey. The results for the United States (U.S.) and the United Kingdom (UK) are shown.
What is the approximate difference between the percent of U.S. drivers and the percent of UK drivers who reported talking on their cell phone while driving?
A. 75%
B. 50%
C. 25%
If you subtract the 'yes' on the R graph from the 'yes' on the L graph, you can envision that about 1/2 of the circle on the L still remains
1/2 is 50 percent..... this is a tricky worded question....but that is the answer I would submit.
