Question

According to the column relative frequency table, find the relative frequency of girls that have black hair.

  1. 40%
  2. 25%
  3. 44%
  4. 20%

hintHint:

Data is a collection of information, which can be presented in many forms. One of them is tabular form in which data can be analysed and it helps to understand the data. Here, we have to find the percentage/ relative frequency using the data given in the table.

The correct answer is: 25%


    In the question there is a table using which we have to find the relative frequency of girls that have black hair.
    According to the table given in the question, 
    Total number of girls student= 20
    Number of girls have black hair=5
    Relative frequency=fraction numerator f r e q u e n c y over denominator s u m space o f space a l l space f r e q u e n c i e s end fraction
    Here, the frequency=5
    Sum of all frequencies=20
    Relative frequency= 5 over 20
    Percentage= fraction numerator f r e q u e n c y over denominator s u m space o f space a l l space f r e q u e n c i e s end fraction cross times 100
    =5 over 20 cross times 100
    =25%
    So, the relative frequency is 25%.
    Therefore, the correct option is b, i.e., 25%.

    Relative frequency represents the number of times an event has occurred. It can be determined using the formula fraction numerator f r e q u e n c y over denominator s u m space o f space a l l space f r e q u e n c i e s end fraction.
