Answer:
[tex]\bold{\boxed{R Intersection S = {20} }}[/tex]
Step-by-step explanation:
The intersection in a sample is the reoccurring numbers that are present.
Let's list the two samples:
R = {10, 15, 20}
S = {20, 25}
The number 20 is present in both samples, so -
R Intersection S = {20} !
Hope it helps! :)
