Set \(B\)

Set \(A\)

\(A\) is a Proper Subset (\(A \subset B\)): All elements of \(A\) are in \(B\), and \(A \neq B\).

🍓 🍎

Set \(A = \{\text{🍓, 🍎}\}\)

\(\subset\)

🍓 🍎 🍊 🍌

Set \(F = \{\text{🍓, 🍎, 🍊, 🍌}\}\)

In this case, \(A\) is a Proper Subset of \(F\) because \(A \subset F\) and \(A \neq F\).

🧺 Drag and Drop: Build the Fruit Sets

Drag the fruits from the "Market" into the correct sets based on the rule: Set \(A\) contains only berries and pome fruits, while Set \(F\) contains all available fruits.
