For P = {1, 6, 10, 14}, Q = {1, 5, 11), and R = {3, 5, 10, 11), find P U (Q U R). The answer is { }

(Use a comma to separate answers as needed.)

Step-by-step explanation:

p union ( Q union R)

let solve for d elements inside d bracket

p = 1,6,10,14 Q = 1,5,11

R = 3,5,10,11

union means joining elements that is p with R.if there is occurrence just pick one.

(Q u R ) = ( 1,3,5,10,11)

so p u ( Q u R ) = ( 1,3,5,6,10,11,14)
