Question

If A and B are two disjoint sets and n(A)=25, n(B)=15 find n (A union B) and n(A interjection B)

[Answer Step-by-Step]​

Answer 1

this the answer for your question bro

Step-by-step explanation:

Given that, A and B are two disjoint sets

n(A)=15 and n(B)=10

Then,

n(A⋂B)=0 becauseA and B both are disjoint

n(A⋃B)=n(A)+n(B)−n(A⋂B)

n(A⋃B)=15+10−0

n(A⋃B)=25

Hence, this is the answer

Answer 2

n(AUB) = n(A) +n(B)
= 25+15=40

n(A intersection B) = nothing or we can say a null set because it is a disjoint set
