If probability of simultaneous occurrence of two events A and B is p and the probability that exactly one of A, B occurs is q, then which of the following is/are correct?

1. P($$\overline A $$) + P($$\overline B $$) = 2 $$-$$ 2p $$-$$ q

2. P($$\overline A $$ $$\cap$$ $$\overline B $$) = 1 $$-$$ p $$-$$ q

Select the correct answer using the code given below.

Two integers x and y are chosen with replacement from the set [0, 1, 2, ........., 10]. The probability that | x $$-$$ y | > 5 is
