Suppose P={0,1,2,3,4,5,6,7,8,9} and V={2,4,6,8,10,12,14,16,18,20}. What is P⌒V?

a. {0,1,2,3,4,5,6,7,8,9,10,12,14,16,18,20}
b. {0,1,3,5,7,9}
c. {10,12,14,16,18,20}
d. {2,4,6,8}

assume your symbol is upside down U or intersection, in both where circles overlap

2 in both
4
6
8
even numbers up to 8

looks like d
