Question

Given the following sets.

A = {0, 1, 2, 3}
B = {a, b, c, d}
C = {0, a, 2, b}

Find B∪C

1. {0, 1, 2, 3}
2. {a, b, c, d}
3. {0, a, 2, b}
4. {a, b, c, d, 0, 2}
5. Empty Set

Answer 1

that's the uniion of sets B and C
that means inclde all the values of both sets (not meaning the ones common to both sets)


so that would include a,b,c,d, 0,a,2,b
a and b repeat so list them only once


that would be {a,b,c,d,0,2}
answer is 4th option
