-have wheels or have engines

.

the set r∩s is the set of things that
-have wheels and have engines
-have wheels or have engines
.

the set r′ is the set of things that
-don't have engines

1. The set R ∪ S is the set of things that:

* have wheels or have engines

2. The set R ∩ S is the set of things that :

* have wheels and have engines

3. The set R′ is the set of things that :

Step-by-step explanation:

Let's complete the sentences:

1. The set R ∪ S is the set of things that:

* have wheels or have engines

Let's recall that the union of two sets, R and S for our case, is the set of elements which are in R or in S or in both.

2. The set R ∩ S is the set of things that :

* have wheels and have engines

Let's recall that the intersection of two sets, R and S, is the set of elements that are common to both R and S.

3. The set R′ is the set of things that :

* don't have wheels but do have engines

Let's recall that the complement of a set, R is the set of all elements that are in the universal set but are not in R. R' = {x ∈ U : x ∉ R}.

Our universal set is the set of things that have wheels or have engines and the complement of R is the set of things that don't have wheels but do have engines.
