Answer:
Tossing 2 coins
Explanation:
Tossing 2 coins is the simplest event of the set. It's an event that's guaranteed to happen.
Spinning "lose a turn" on a spinner and drawing a club from a deck of cards is probability-dependent and is not very simple or likely to happen.
Rolling an even number on a die and spinning red on a spinner also relies on probability.
Drawing the two of hearts from a deck of cards sounds pretty simple, right? However, the odds of this happening isn't likely and relies on probability.
