The results of a survey asking 100 people how they get their news.
15 From newspapers;
25 From television;
40 From both newspapers & Television
and 20 from no sources;

What is the probability that a person selected at random from this survey does NOT claim television as a source of getting the news?

Probability 
Anonymous,
65 people (25 + 40) cite television as a news source
so 35 out of 100 people do NOT claim TV as a source
