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