The life of Sunshine CD players is normally distributed with a mean of 4.1 years and a standard deviation of 1.3 years. A CD player is guaranteed for 3 years. We are interested in the length of time a CD player lasts. Find the probability that a CD player will break down during the guarantee period. Sketch the situation. Label and scale the axes. Shade the region corresponding to the probability. P(0 < x < ____________) = ___________ (Use zero for the minimum value of x.)
