Question
The given statements is corect? Write a correct form of the given incorrect statements.$\{\text{a}\}\subset\{\{\text{a}\},\text{b}\}$
✓

Answer

False.Explanation:
$\because$ {a} is not a subset of {{a},b} hence it cannot be contained in it. The correct form is $\{\text{a}\}\in\{\{\text{a}\},\text{b}\}$ Another correct form could be $\{\{\text{a}\}\}\subset\{\{\text{a}\},\text{b}\}.$
