Question

The table below shows a random sample data to analyse the preference of music among the people at various clubs.
Calculate the percentage of people who doesn't prefer the genre rock.

• A. 75%
• B. 50%
• C. 24%
• D. 26%

Answer 1

The correct option is B 50%

In the given sample,

Here,
Sample size = 24 + 26 + 50 = 100

Number of people who prefer rock = 50
Number of people who doesn't prefer rock = 100 - 50 = 50

Percentage of people who doesn't prefer pop:
$=\frac{\text{Number of people who prefer genre other than rock}}{\text{Sample size of the data}}$
$=\frac{50}{100}\times 100\%=50\%$

$\therefore$ Percentage of people who doesn't prefer the genre rock are 50%.
