How to complete the relative frequency table?

First we look at the row total of people who like to fly, which is of 70%, hence:

  • It is stated in the table that the proportion of those who like to fly and can drive is of 0.32.
  • Hence the relative frequency of those who like to fly and cannot drive is of: 0.7 - 0.32 = 0.38.

Amount those who can drive, we have that:

  • The total is of 0.45.
  • 0.32 like to fly.
  • Hence the relative frequency of those who do not like to fly is of: 0.45 - 0.32 = 0.13.

Amount those who cannot drive, we have that:

  • The total is of 0.55.
  • 0.38 like to fly.
  • Hence the relative frequency of those who do not like to fly is of: 0.55 - 0.38 = 0.17.

Thus the total frequency of the second row is given as follows:

0.17 + 0.13 = 0.30.
