The table below shows the relative frequencies of the color of cars bought last month by males and females. which percentage represents the car bought most often? options: 20% 31% 43% is wrong 57% (i already did my other questions, this is the only one i needed with)

The first thing we must do for this case is to observe the highest relative frequency of the table in the total column.
 For the white car we have:
 Male = 0.11
 Female = 0.20
 Total = 0.31
 The percentage is given by:
 (0.31) * (100) = 31%
 
 The percentage that represents the car bought most often is:
 31%

The answer is b: step 2.
