Question

the following sets are given.
a = {9, 10, 11, 12, 13}
b = {8, 9, 10, 11, 12}

are the sets equal?
○ yes
○ no

Explanation:

Step1: Recall set equality rule

Two sets are equal iff they share all identical elements.

Step2: Compare elements of A and B

$A = \{9, 10, 11, 12, 13\}$, $B = \{8, 9, 10, 11, 12\}$. $A$ has 13 (not in $B$), $B$ has 8 (not in $A$).

Answer:

No
