Question 1153907
<br>
The percentage that purchase either a golf club or golf balls or both is (10+30)-6 = 34.<br>
(Count the customers who buy a golf club and add the number who buy golf balls; then subtract the number who buy both, because you have counted them twice.)<br>
So the percentage who buy neither is 100-34 = 66.<br>
ANSWER: 66% buy neither golf clubs nor golf balls<br>
