Question

If n (A U B) = 30 n(A n B) = 10 Find n(A) + n (B) plz tell me ans step by step ​

Answer 1

Answer:

n(A)+n(B) = 40

Step-by-step explanation:

If n (A U B) = 30 ,n(A n B) = 10

/* We know that,

n(A)+n(B) = n(AUB)+n(AnB)

= 30 + 10

= 40

Therefore,

n(A)+n(B) = 40

Answer 2

Answer :

n(A) + n(B) = 40

Step-by-step explanation :

Given Data -

n(A) + n(B) = 40

n(A n B) = 10

To Find -

n(A) + n (B)

Solution -

As we know -

$\bigstar\;\boxed{\sf n(A)+n(B) = n(AUB)+n(AnB)}}$

So,

➟ 30 + 10

➟ 40

Therefore,

n(A) + n(B) = 40
