If a real number x is chosen at random in the interval [0,4] and a real number y is chosen at random in the interval [0,5], what is the probability that x < y?  Select the correct option:	A) 3/5	B) 2/5	C) 7/10	D) 3/4	E) 2/3
Since x is in [0,4] and y is in [0,5] we can draw a rectangle in the coordinate plane with vertices (0, 0), (4, 0), (0, 5), and (4, 5).   The points above the line y=x satisfy x &lt; y.   The part of the rectangle below y=x has an area of 8.   The whole rectangle has an area of 20.   P(x &lt; y) = (20-8)/20 = 12/20 = 3/5   The answer is 3/5.
