Question

Given the following sets.

A = {0, 1, 2, 3}

B = {a, b, c, d}

C = {0, a, 2, b}


find B u C

a. {0, 1, 2, 3}

b. {a, b, c, d}

c. {0, a, 2, b}

d. empty set

e. {a, b, c, d, 0, 2}

Answer 1

`\large\boxed{e.\ \{a,\ b,\ c,\ d,\ 0,\ 2\}}`

Explanation:

`\text{The union (denoted by}\ \cup\ \text{) of a collection of sets is the set of all elements of the sets. }\\\\A=\{0,\ 1,\ 2,\ 3\}\\\\B=\{a,\ b,\ c,\ d\}\\\\C=\{0,\ a,\ 2,\ b\}\\\\B\ \cup\ C=\{a,\ b,\ c,\ d,\ 0,\ 2\}`
