A∩B means the set of elements that are common (or the same) in two sets: A and B. Sometimes you will have no elements that are the same between two sets and you will indicate this as {} meaning empty set. The symbol ∩ is known as intersection of two sets. You will set-up the problem as follows:
A = {2, 6, 10, 14, 18, 22, 26, 30} and
B = {-6, -3, 5, 10, 16, 22, 30, 42}
{2, 6, 10, 14, 18, 22, 26, 30} ∩ {-6, -3, 5, 10, 16, 22, 30, 42}
= {10, 22, 30}
I am assuming for #10 you want subsets of {2, 9}.
Let P(S) stand for Power Set of S,therefore your subsets will be
P(S) = P({2,9}) = {},{2},{9},{2,9}.
Of the 125 students in an elementary school, some only play checkers, some only play chess, and some play both. 89 students play checkers and 45 students play checkers and chess. How many students in the school play chess
If A = {2, 6, 10, 14, 18, 22, 26, 30} and B = {-6, -3, 5, 10, 16, 22, 30, 42}, what is A∩B?
