Use a membership table to show that A ∩ (B ∪ C) = (A ∩ B) ∪ (A ∩ C).
Compute the area of the plane region bounded by the curve x=y2-2 and the line y=-x using integration along the y-axis.
What is the symbolic word if Caroline is late (l), we will not pursue our plan (~p). We did not pursue our plan. Therefore, Caroline was late.
There is a spinner with 11 equal areas, numbered 1 through 11. If the spinner is spun one time, what is the probability that the result is a multiple of 2 or a multiple of 3?
