Answer:
The relative frequency of rows for the data is
                    Learn baseball   Do not learn baseball    Total
Learn basketball           0.63             0.37               1
Do not learn basketball     0.84             0.16               1
Total                    0.72             0.28               1
Step-by-step explanation:
Given information:
Members who learned baseball = 84
Members who learned baseball and basketball = 42
Students who did not learn baseball but learned basketball =25
Students did not learn either baseball or basketball = 8
Using the above information draw a frequency table as shown below:
                    Learn baseball   Do not learn baseball    Total
Learn basketball           42               25               67
Do not learn basketball     42               8               50
Total                     84               33              117
To find the relative frequency for the data, we divide each element of by the total observations, i.e., 117.
But, to find the relative frequency of rows for the data, divide each element of row by the total of rows.
The relative frequency of rows for the data is
                    Learn baseball   Do not learn baseball    Total
Learn basketball           [tex]\frac{42}{67}\approx 0.63[/tex]        [tex]\frac{25}{67}\approx 0.37[/tex]          1
Do not learn basketball     [tex]\frac{42}{50}=0.84[/tex]        [tex]\frac{8}{50}=0.16[/tex]            1
Total                    [tex]\frac{84}{117}\approx 0.72[/tex]        [tex]\frac{33}{117}\approx 0.28[/tex]          1
