Question

Which of the following expression is equivalent to the intersection of R and S:

Select one:
a. R - S
b. S - (R - S)
c. R - (S - R)
d. R - (R - S)

Answer 1

The intersection of R and S is represented by the expression R - (R - S).

Step-by-step explanation:

The intersection of R and S is the set of elements that are common to both sets R and S. In other words, it consists of all the elements that are in both R and S.

Out of the given options, the expression that represents the intersection of R and S is d. R - (R - S).

This is because when we subtract the elements in R that are not in S from R, we are left with the intersection of R and S. It ensures that only the common elements are included in the final result.
