Illustrate an abstract mathematical concept without any text. The image should represent four distinct sets. Set U should be slightly larger and contain thirty divisions to indicate each of the positive integers less than or equal to 30. Set M should contain ten visible divisions, symbolising all even positive numbers up to 20. Set N should have ten indented wholes, showing odd numbers up to 19. And lastly, set S should be depicted with 21 components to represent all integers between 10 and 30. All sets should be colored vividly different to distinguish from each other.

U= { 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)

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)

surely you can count.

n(U) = 30
n(N') = n(U) - n(N) = 30 - 10 = 20
and so on.

what would be the elements of S={all integer x: 10<=X<=30}

I don't understand how you guy solve this question you did not even show the working.

(i) 30

( ii) 20
( iii)31
( iv)29
( v)20

U = 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30

M= 2,4,6,8,10,12,14,16,18,20
N = 1,3,5,7,9,11,13,15,17,19
S = 10,11,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30
n(U) = 30
n(N') = 20
n(N) +n(S) =10+21= 31
n(M')+n(S') = 20+9=29
n(M)+n(N)= 10+10=20

NB: Read complementary and cardinality set.
Good luck!

Pleas show the workings

I do not understand the last question

I get the question but cannot solve

n(n¹)=30
