Answer:
P U (Q∩R)={3, 5, 6, 10, 13, 15}
Step-by-step explanation:
The first step that we have to do is find (Q∩R) then, we ned to find the elements in common between Q and R, as we can see we have the element 6 and the element 13, then:
(Q∩R)={6, 13}
Now we just need to do the union between P and (Q∩R), that is just put all the elements of P and (Q∩R) in one set, then:
P U (Q∩R)={3, 5, 6, 10, 13, 15}
