To calculate the relative frequency by row of students who like both tacos and pizza, we need to divide the number of students who like both tacos and pizza by the total number of students in each row.
From the table, the number of students who like both tacos and pizza is 57.
The total number of students who like tacos is 69, so the relative frequency for students who like both tacos and pizza in that row is:
57/69 = 0.83
Therefore, the relative frequency by row of students who like both tacos and pizza is 0.83.
The table shows the number of students in a school who like tacos and/or pizza:
Like Tacos Do Not Like Tacos Total
