Explanation:

Step1: Count occurrences of 'R'

Count the number of 'R's in the data. There are 5 'R's.

Step2: Calculate relative - frequency of 'R'

Relative frequency of 'R' = $\frac{5}{20}=0.25$

Step3: Count occurrences of 'D'

Count the number of 'D's in the data. There are 5 'D's.

Step4: Calculate relative - frequency of 'D'

Relative frequency of 'D' = $\frac{5}{20}=0.25$

Step5: Count occurrences of 'G'

Count the number of 'G's in the data. There is 1 'G'.

Step6: Calculate relative - frequency of 'G'

Relative frequency of 'G' = $\frac{1}{20}=0.05$

Step7: Count occurrences of 'I'

Count the number of 'I's in the data. There are 9 'I's.

Step8: Calculate relative - frequency of 'I'

Relative frequency of 'I' = $\frac{9}{20}=0.45$

Answer:

Value	Frequency	Relative Frequency
D	5	0.25
G	1	0.05
I	9	0.45
