Asked by Mr.Brain

In a marketing survey involving 1,000 randomly chosen people, it is found that 630 use brand P, 420 use brand Q, and 210 use both brands. How many people in the survey use brand P and not brand Q?

dont tell me the answer just tell me how to do it
Answered by Dr. Jane
You have to subtract the overlap of 210 from 630 and that will just be P and won't include any Q.
