Answer:
.25 .75
.44 .56
Step-by-step explanation:
To find the relative frequency, we take the part over the total.
Since this is a relative frequency table, the total for each row is 1
Group 1 A = 15/ (15+45) = 15/60 = .25
Group 1 B = 45/(15+45) = 45/60 = .75
Group 2 A = 20 /(20+25) = 20/45 =.44
Group 2B = 25/(20+25) = 25/45 =.56
