Please explain step-by-step:

Assume source elements of length 6 are mapped in some uniform fashion into target elements of length 3. Each digit can take on one of 9 possible values. Thus the number of source elements is 531,441 and the number of target elements is 729. A particular source element x is mapped to a target element y If the adversary is given element y, what is the probability the correct source element can
