Power Set Probability Event E
Let S be a set of 5 elements and P(S) denote the power set of S. Let E be an event of choosing an ordered pair (A, B) from the set P(S) × P(S) such that A 
B = 
. If the probability of the event E is 
where p, q ∈ ℕ, then p + q is equal to
B = . If the probability of the event E is where p, q ∈ ℕ, then p + q is equal to
