Question

Let x denote the amount of gravel sold (in tons) during a randomly selected week at a particular sales facility. Suppose that the density curve has height f(x) above the value x, where

The density curve (the graph of f(x)) is shown in the following figure:

 

S 2(1 – x) 0< x< 1
f (x) =
otherwise

Use the fact that the
Area of a triangle = (Base) (Height) to calculate each of the following
probabilities. (Hint: Drawing a picture and shading the appropriate area
will help.)
a. P (x < )
b. P (xs )
c. P (x < )
d. P ( <x<) (Hint: Use the results of Parts (a)-(c).)
