Redundant Rupture Disks

A tank rated for a maximum allowable working pressure (MAWP) of 50psig has two rupture disks. Both of the rupture disks are identical, and are rated for 30psig \( \pm \) 2psig. Assume that the probability of bursting follows a uniform distribution over the specified tolerance for each disk. Find the expected pressure at which the tank will have its pressure relieved, assuming that the rupture disks burst instantly. Give your answer in psig rounded to 4 decimal places.
