The joint and marginal relative frequencies calculated in the table if she teaches 75 geometry students in total.
What is a conditional relative frequency?
It is defined as the frequency that can be evaluated by the two-way frequency table. Usually, we can obtain this frequency by dividing the frequency that is not in the total frequency cell to total frequency.
We have a table shown in the picture with data.
We can find the joint and marginal relative frequencies:
For the first cell:
= 12/21 = 4/7
For the second cell:
= 9/21 = 3/7
For the fourth cell:
= 18/30 = 3/5
Similarly, we can find for rest of the cells:
Thus, the joint and marginal relative frequencies calculated in the table if she teaches 75 geometry students in total.
