Answer: A B
Group A 0.25 0.75
Group B 0.45 0.55
Step-by-step explanation:
Since we have given that
Number of people of A in Group A = 15
Number of people of B in Group A = 45
Number of people of A in Group B = 20
Number of people of B in Group B = 25
Total number of people in Group A = 15+45 = 60
Total number of people in Group B = 20+25 = 45
So, Relative frequencies will be given below:
Relative frequency of A in Group A is given by
[tex]\frac{15}{60}=0.25[/tex]
Relative frequency of B in Group A is given by
[tex]\frac{45}{60}=0.75[/tex]
Relative frequency of A in Group B is given by
[tex]\frac{20}{45}=0.45[/tex]
Relative frequency of B in Group B is given by
[tex]\frac{25}{45}=0.55[/tex]
Hence, A B
Group A 0.25 0.75
Group B 0.45 0.55
