A point (x,y) is randomly selected such that 0 <= x <= 3 and 0 <= y <= 8. What is the probability that x + y <= 4? Express your answer as a common fraction.

See the graph below....

 the trapezoid represents  x + y < 4     area =  7.5

   total double shaded rectangle area = 24

 

7.5/ 24 = 15/48    = 5/16
