Answer the following with the help of the table

What is the conditional relative frequency of the males in the table?

  1. 21 over 60
  2. 21 over 240
  3. 21 over 156
  4. None of the above

The correct answer is: 21 over 60


    c o n d i t i o n a l space r e l a t i v e space f r e q u e n c y equals fraction numerator J o i n t space r e l a t i v e space f r e q u e n c y over denominator M a r g i n a l space r e l a t i v e space f r e q u e n c y end fraction
    Joint relative frequency for male=21 over 240
    Marginal relative frequency for male=60 over 240
    Conditional relative frequency for male=
    space space space fraction numerator begin display style 21 over 240 end style over denominator begin display style 60 over 240 end style end fraction
equals fraction numerator 21 cross times 240 over denominator 60 cross times 240 end fraction
equals 21 over 60
