A = { 1 5 , 2 , 6.1 , 10 } and B = { 2 , 10 , 11 } . Find A ∪ B .

Sagot :

Answer: A ∪ B = { 2, 10 }

Step-by-step explanation:

      A ∪ B asks us to write the elements between sets A and B. In other words, we are being asked to find the union of the two sets.

             A = { 15 , 2 , 6.1 , 10 }

             B = { 2 , 10 , 11 }

      There are five elements that show up across both sets. A ∪ B can be written as:

             A ∪ B = { 2, 6.1, 10, 11, 15 }
