Given is a table of Relative frequencies of a game-survey.

Ages------------Strategy games---Role-playing games------Total

Ages 11–20: 0.25 0.21 = 0.46

Ages 21–30: 0.31 0.23 = 0.54

We can see from the table, Total frequency of people in the age "group 11-20" are 0.46

Hence, final answer would be 0.46 or 46%.
