Mathematics, 25 like Science and 15 like both. Then,
the number of students who like either Mathematics
or Science is

Answer 1

Answer:

40 students is right answer

Step-by-step explanation:

N(m) = 30,N(s)=25, N(MnS)= 15

we have to find N(MuS)= ?

SO, N(MuS)=N(M)+N(S)-N(MnS)

N(MuS)=30+25-15

N(MuS)=40

Answer 2

Answer:

40

Step-by-step explanation:

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

x : 30+25-15

x:40
