Question

*If n( A) = 62 , n(B) = 54 . A and B are disjoint sets then n ( A ∩ B ) = ?*

1️⃣ 62
2️⃣ 0
3️⃣ 54
4️⃣ 116​

Answer 1

Step-by-step explanation:

given n(A) = 62 and n(B) = 54

n(AnB) = n(A) + n(B) - n(AuB)

= 62 + 54 - 0

here, A and B are disjoint sets

therefore n(AuB) = 0

= 116

answer : Option - 4
