Question

Given the following sets, select the statement below that is NOT true.
A = {b, l, a, z, e, r}, B = {b, a, l, e}, C = {a, b, l, e}, D = {l, a, b}, E = {a, b, l}
(Points : 2)
E ⊆ A
C ⊆ B
D ⊆ C
D ⊂ B
C ⊂ B

Answer 1

Hi tjcjsha, do you know what the symbols \(\subset , \subseteq\) mean? Without that, it's very difficult to explain the answer to this problem.

Answer 2

yes i know

Answer 3

here, We know that B and C have same elements so they are equal.
So, B=C
Similarly D=E and every set is a subset of A.
Now the answers would be
1.E\[\subseteq\]A

2.C\[\subseteq\]B

3.D\[\subseteq\]C

and D\[\subset\]B

P.S- how do i get the sign between these 2 words? Please help me.

Answer 4

\ ( \ ) instead of \ [ \ ]

Answer 5

Thanks
