I'm working on a Venn diagram - would you please check my work?

The question is:

A group of 95 respondents said they regularly watch Netflix, 60 said they watch Hulu, 20 said they watch neither Netflix or Hulu, and 35 said they watch both Netflix and Hulu.

1. How many respondents watch only Netflix?

I said 60 because 95 - 35 (the number that watches both) = 60

2. How many respondents participated in the survey?

I said 150:
Netflix had 60 (as stated above)
Both Netflix and Hulu: 35
Hulu: 25 (60 - 35 from both = 25)
None: 20

So 60 + 35 + 25 + 20 = 150

Would these answers be correct?

Thank you.

  1. John

    60 +35+25+20 = 140
    but your logic is good.
    And your answer of 60 for just Netflix is correct as well : )
