Question

n(A)=25 n(B) = 15 and disjoint sets then n(A-B)=

answer this question I will mark you as brainliest

Answer 1

Answer:

N(A-B) = 10.

Step-by-step explanation:

A and B are disjoint sets .

So , N(A-B) = 10

N(A-B) = N(A) - N(B)

N(A-B) = 25-15

N(A-B) = 10

Hope this helps you.

Thanks.

* The formula used here is :

N(A-B) = N(A) - N(B).

Answer 2

Answer:

Given that, A and B are two disjoint sets

n(A)=25 and n(B)=15

Then,

n(A-B)=10 becauseA and B both are disjoint

n(A-B)=n(A)-n(B)

n(A-B)=25-15

n(A-B)=10

Hence, this is the answer.
