Answer:
nswer: n(A U B) = 15 and n(A ∩ B) = 0.
Step-by-step explanation: Given that A and B are two disjoint sets with
n(A) = 15 and n(B) = 10.
We are to find n(A U B) and n(A ∩ B).
We know that
the intersection of two disjoint sets is an empty set.
That is,
From set theory, we have
Thus, n(A U B) = 15 and n(A ∩ B) = 0.
