Determine whether the following statement is true or false.
{a} Є {a, b, c, d, e}
Solution:-
The symbol Є means “is an element of.”
For example, the statement b Є {a, b, c, d, e} is true because b is an element of {a, b, c ,d, e}.
The statement f Є {a, b, c, d, e} is false because f is not an element of {a, b, c, d, e}.
The statement {b} Є {a, b, c, d, e} is false because {b} refers to the set containing b as its only element. Although b is an element of {a, b, c, d, e} is not.
Therefore, {a} Є {a, b, c, d, e} is not a true statement.
