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?

You have to subtract the overlap of 210 from 630 and that will just be P and won't include any Q.

To put the answer straight it's 420

To determine the number of people who use brand P and do not use brand Q, we need to calculate the difference between the total number of people who use brand P and the number of people who use both brands.

Here's how to do it:

1. Identify the total number of people who use brand P: 630.
2. Identify the number of people who use both brand P and Q: 210.
3. Subtract the number of people who use both brands (210) from the total number of people who use brand P (630): 630 - 210 = 420.

Therefore, there are 420 people in the survey who use brand P but do not use brand Q.
