Question

Given A = {a, e, i, o, u} and B = {a, l, g, e, b, r}, find A ∪ B.

(A ) - {}
(B) - {a,e}
(C ) - {a, b, e, g, i, l, o, r, u}

Answer 1

The union of two sets is a new set that contains all of the elements from those 2 sets

A ∪ B = {a, b, e, g, i, l, o, r, u}

answer

(C ) - {a, b, e, g, i, l, o, r, u}

Answer 2

The unition of two sets
`A` and
`B`, written
`A\cup B`, is that set containing all elements in either
`A` or
`B` (or both, since "or" is taken as inclusive here) i.e.:


`A\cup B=\x\in A \lor x\in B\`

Thus:

`A\cup B=\{a,e,i,o,u\}\cup\{a,l,g,e,b,r\}`

`A\cup B`={a,b,e,g,i,l,o,r,u}
