Problem 5.151

The lengths of life Y for a type of fuse has an exponential distribution with a density function given by f (y) = (1/)ey/ , y 0, 0, elsewhere. a If two such fuses have independent life lengths Y1 and Y2, find their joint probability density function. b One fuse from part (a) is in a primary system, and the other is in a backup system that comes into use only if the primary system fails. The total effective life length of the two fuses, therefore, is Y1 + Y2. Find P(Y1 + Y2 a), where a > 0.
