The lifetimes (in years) of a certain kind of electronic component is a random variable having probability density function

f(x) = 5/(x+5)^2 when x>=0

= 0 when x<0

a.) Graph the density function, and describe the shape of the population of component lifetimes. Which is larger - the mean lifetime or the median lifetime?

b.) Compute the probability that a randomly selected component survive at least two years.
