The current in a certain circuit as measured by an ammeter is a continuous random variable X with the following density function:
a. Graph the pdf and verify that the total area under the density curve is indeed 1.
b. Calculate P(X ≤ 4). How does this probability compare to P(X <, 4)?="">
c. Calculate P(3.5 ≤ X ≤ 4.5) and also P(4.5 , X).
