Mark me as a Brainliest pls

Step-by-step explanation:

Given :-

A C B

n(A) = 50

n(B) = 60

Find :-

n(A U B)

Solution :-

We know that

n(A U B) = n(A) + n(B) - n (A∩B)

Here

A C B so A∩B is 50

n(A U B) = n(A) + n(B) - n (A∩B)

n(A U B) = 50 + 60 - 50

n(A U B) = 60

Conclusion :-

n(A U B) = 60
