Question

list all the formula of chapter set?

Answer 1

Step-by-step explanation:

n(AᴜB) = n(A) + (n(B) – n(A∩B).

n(AUBUC) = n(A) + n(B) + n(C) – n(A⋂B) – n(B⋂C) - n(C⋂A) + n(A⋂B⋂C).

If n(A∩B)= 0 then AᴜB = n(A) + n(B).

n(A - B) + n(A∩B) = n(A).

N(B - A) + n(A∩B) = n(B).

n(AᴜB) = n(A - B) + n(A⋂B) + n(B - A).
