<font color=black size=3>
Hints
A = {2,4,6,8,10,12}
B = {5,6,7,8,9,10,11,12}
Notation like n(A) means "the number of values in set A".


*[tex \large A \cap B] is the intersection of sets A and B
It's the set of elements found in both sets
For example, if A = {p,q,r} and B = {r,s,t,p} then *[tex \large A \cap B = \{p,r\}]
