The two-way frequency table of column relative frequencies for Kamden is shown below.
What is a two-way frequency table?
A two-way frequency table is a table that's used to graphically the represent frequencies or relative frequencies that are associated with two categorical variables.
How to complete the two-way frequency table?
When card had a star, the relative frequency that Kamden guessed a star is given by:
F(s) = 4/5
F(s) = 0.80.
Kamden guessed not a star is given by:
F(ns) = 2/754
F(ns) = 0.002 ≈ 0.00.
When card didn't have a star, the relative frequency that Kamden guessed a star is given by:
F(s) = 1/5
F(s) = 0.20.
Kamden guessed not a star is given by:
F(ns) = 752/754
F(ns) = 0.997 ≈ 1.00.
For the total, we have:
Total of F(s) = 0.80 + 0.20
Total of F(s) = 1.00.
Total of F(ns) = 0.00 + 1.00
Total of F(ns) = 1.00.

Complete Question:
Kamden is a mind-reading alien. He had each friend draw and look at a card, then he guessed whether the card had a star on it. The two-way frequency table below shows data on guess and true status of the cards the friends drew. Complete the following two-way table of column relative frequencies. (If necessary, round your answers to the nearest hundredth.)
