MCQ

Given $A = \{a, b, c, d, e, f, g, h\}$ and $B = \{a, e, i, o, u\}$ then $B - A$ is equal to:

✓
$\{i, o, u\}$
B
$\{a, b, c\}$
C
$\{c, d, e\}$
D
$\{a, i, z\}$

✓

Answer

Correct option: A.

$\{i, o, u\}$

The sets $A = \{a, b, c, d, e, f, g, h\}$ and $B = \{a, e, i, o, u\},$ in order to find the difference between the two sets as $B−A,$ we begin by writing all the elements of $B$ and then take away every element of $A$ which is also the element of $B.$
Since $B$ share the elements a, e with $A,$
so $B - A = \{i, o, u\}.$
