Answer:

cant understand your question

Answer 2

Answer:12,

Step-by-step explanation:

n(u) = n(NuEuM)

=20

n(N)=14

n only(N)

=4

n(E)=8

n only EnM

=0

Let n only NnE is x and NnM is y

nEnNnM is

So, x+3=

or, x=

and,y+x+3+4=

or,y=

now, n only (M)=20-4+2+3+5

. Or,. =6

again,n only (NuM)=4+2+6=122
