A transmission repair firm that wants to offer a lifetime warranty on its repairs has determined that the probability density function for transmission failure after repair is shown below, where t is the number of months after repair. (Round your answers to three decimal places.) f(t) = 0.3e-0.3t (a) What is the probability that a transmission chosen at random will last 5 months or less? (b) What is the probability that a transmission chosen at random will last more than 5 months?
