Question

in a survey of hundred people it was found that 65 like frocks and 55 like modern song and 35 liked flok as well as modern some find how many people do not like both song ​

Answer 1

Answer:

15 people don't like either song.

Step-by-step explanation:

• First, take 35 away from both preferences to work out the amount of people who ONLY LIKE 1 GENRE.

       FROCKS: 65 - 35 = 30 people

       MODERN: 55 - 35 = 20 people

• This means that 30 people like frock, 20 people like modern and 35 like both; this means 85 people liked at least 1 of the 2 genres.
• Take this away from 100 to work out how many people liked NOTHING:

        100 - 85 = 15 people
