A bowl contains nine stones, numbered 1–9. We select successively six stones, without replacement, and write down the six-digit number that is produced from the numbers on the selected stones (in the order that they were selected).

(i) Find the probability that this six-digit number does not include the numbers 2 and 5.

(ii) What would be the answer to Part (i) if the sampling of the stones from the ball was with replacement?
