Question

(d) If n(A) = n(B) = 60 and set A and set B for disjoint sets,find n(AUB)​

Answer 1

The difference of two numbers is 28.If the smaller number is 10,find the greater one.

Explanation:

.

Answer 2

Explanation:

Given that n(A) = n(B) = 60, we can find n(A ∪ B) as follows:

formula to calculate n(A ∪ B) is n(A) + n(B)

So,

n(A ∪ B) = n(A) + n(B)

n(A ∪ B) = 60 + 60

n(A ∪ B) = 120

So, the cardinality of the union of sets A and B (n(A ∪ B)) is 120.
