1. Universal set (Ù) = { all positive integer less than or equal to 30}
M={all even positive numbers less than or equal to 20}
N={all odd number less than or equal to 19}
S={all integer x: 10<=X<=30}
find. i. n(U) ii. n(N') iii. n(N) + n(S) iv. n(M') + n(S) v. n(M) + n(N)

2. surely you can count.
n(U) = 30
n(N') = n(U) - n(N) = 30 - 10 = 20
and so on.
