A bicycle lock requires a two-digit code of numbers 1 through 9, and any digit may be used only once. Which expression would determine the probability that both digits are even?

A - P(both even) = (4P1)(3P1)/9P2

B - P(both even) = (4C1)(3C1)/9C2

C - P(both even) = (5P1)(4P1)/9P2

D - P(both even) = (5C1)(4C1)/9C2

Isee the amount was $90.00 then reduced to $75.00 , what is the percent ?
