Question

Can anyone tell me the answer
​

Answer 1

Answer:

c

Step-by-step explanation:

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

= m-p

similarly,

n(B-A) = n-p

n(A-B)+n(B-A)= m-p+n-p

=m+n-2p

Answer 2

n(A-B)+n(B-A)

=n{A-(A intersection B)}+n{B-(A intersection B)}

=n{A-p}+n{B-p}

=m-p+n-p

=m+n-2p Ans.(c)

So option c is the correct answer.
