Suppose that A is the set of sophomores at your school and B is the set of students in discrete mathematics at your school.
a) It is the intersection A ∩ B
b) This is the difference A − B.
c) It is the union A ∪ B.
--- ---
d) It can be shown as A ∪ B. (bar over A and B both)
This is the theoretical probability
Answer:
The answer is B. X > -2

The traditional area formula for a square is to square a side.
However, Wkipedia has a formula if you are given just a diagonal:
Area = (diagonal)^2 / 2
Area = (24)^2 / 2
Area = 576 / 2
Area = 288 square meters
