Question

N(A)=26, n(B)=17, and n(A∩B)=0, then what is n(A∪B)?

Answer 1

n(A∪B) is 43.

Explanation:

We can use the formula for the union of two sets to find n(A∪B), which is:

n(A∪B) = n(A) + n(B) - n(A∩B)

Substituting the given values, we get:

n(A∪B) = 26 + 17 - 0

n(A∪B) = 43

Therefore, n(A∪B) is 43.
