An optical storage device uses an error recovery procedure that requires an immediate satisfactory readback of any written data. if the readback is not successful after three writing operations, that sector of the disk is eliminated as unacceptable for data storage. on an acceptable portion of the disk, the probability of a satisfactory readback is 0.95. assume the readbacks are independent. what is the exact probability that an acceptable portion of the disk is eliminated as unacceptable for data storage?

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
