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?

P(both even) = StartFraction (4 P 1) (3 P 1) Over 9 P 2 EndFraction
P(both even) = StartFraction (4 C 1) (3 C 1) Over 9 C 2 EndFraction
P(both even) = StartFraction (5 P 1) (4 P 1) Over 9 P 2 EndFraction
P(both even) = StartFraction (5 C 1) (4 C 1) Over 9 C 2 EndFraction
