Answer:
(B u C) = {2, 4, 6, 7, 8, 9, 10}
Step-by-step explanation:
A set that contains elements in either set A or set B is referred to as union set.
To (B u C), we have to combine elements of set B and set A together but with no repetition an element.
(B u C)= {2, 4, 6, 8} u {7, 8, 9, 10}
Therefore
(B u C) = {2, 4, 6, 7, 8, 9, 10}
