3. (Total 30%) Let Y denote the Jength of life (in hundreds of hours) of electronic compo-nents. These components frequently fail immediately upon insertion into a system. Ithas been observed that the probability of immediate failure is 1 /3. If a component doesnot fail immediately, the distribution for its length of life has the exponential densityfunction
【題組】(1) (10%) Find the cumulative distribution function for Y.
