An $$n$$-sided die has sides labeled with the numbers $$1$$ through $$n,$$ inclusive, and has an equal probability of landing on any side when rolled. If the die is rolled twice, what is the probability of rolling $$1$$ both times?

(1) If the die is rolled twice, the probability that the two rolls are different is $$80\%.$$

(1) If the die is rolled twice, the probability that the two rolls are equal is $$\dfrac78.$$
