Must show work please!!
Let U = {1, 2, ..., 10} be the universal set, and let • A = {1, 3, 5, 7, 9} • B = {2, 4, 6, 8. 10} • C = {1, 2, 3, 5, 7}
Find:
a) A ∩ B
b) A B ∪
c) A ∩ C
d) A C ∪
e) A C f) B C
Suppose you are watching 10 passengers leaving the airport. Seven of them have a carry-on bag that was carried on the airplane. Four of them have a checked back that they picked up at the baggage claim area. Two of them are on the way to the ticket counter to complain about all of their luggage being lost.
a) How many people do you see carrying luggage?
b) How many people have both a carry-on and a checked bag?
c) How many people have only a carry-on bag?
