Question

S and T are subsets of a universal set, U, such that: U = {a, b, c, d, e, f, g, h, i} S = {a, b, e} T = {a, d, f, g}. What are the elements of S ⋃ T?

Answer 1

S∪B = {a,b,e,a,d,f,g}

Explanation:

According to the Question,

Given, S and T are subsets of a universal set U ( U = {a, b, c, d, e, f, g, h, i} )

And, S = {a, b, e} , T = {a, d, f, g}

Thus, S∪B(S union B) = n(S) + n(T)

S∪B = {a,b,e,d,f,g} (There It contains all the elements present in S & B).
