which is the intersection of the sets p = {1, 2, 3, 4}, q = {4, 5, 6, 7}, and r = {7, 8, 9, 10}?

{7}

null set

{4, 7}

{4}

Step-by-step explanation:

null set

Option B.

Step-by-step explanation:

Intersection of two sets is a set of common terms in both the sets.

Now the two sets are P = {1, 2, 3, 4}, Q = {4, 5, 6, 7} and R = {7, 8, 9, 10}

Common terms in P and Q,

P∩Q = {∅}

Now the common terms in R and (P∩Q).

(P∩Q)∩R = {∅}

Answer is a null set.

Option B, will be the answer.
