Answer:

1/4500

Step-by-step explanation:

The first digit can be one of 9 digits, 1 though 9.

The second and third digits can each be one of 10 digits.

The last digit must be even, so it is one of the five digits, 0, 2, 4, 6, 8.

The total number of different PINs available is:

9 × 10 × 10 × 5 = 4500

p(8564) = 1/4500
