All the following EXCEPT one are correct values for a in the equation: a = x/5 + y/5^2 + z/4^3, where x, y, and z are each equal to 1 or 0.  Select:
A) 15/32	B) 7/64	C) 13/32	D) 1/64	E) 5/32
a = x/5 + y/5^2 + z/4^3   = x/5 + y/25 + z/64   = (25x + 5y + z ) /64   Depending on whether x, y and z take 0 or 1.   Answer 5/32
