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 }
