Question:

A
{2 , 3 , 4 , 5 , 6 , 7 , 8 , 11 , 13}

explanation

The symbol U represents the *union* of two sets; its members are anything that is in either of the two sets whose union is being considered. A = {2 ,4 ,6 ,8} and B = {2 , 3 , 5 , 7 , 11 , 13 }. Therefore A \u222A B = {2 , 3 , 4 , 5 , 6 , 7 , 8 , 11 , 13}. Recall that 1 is not prime.
