Answer:
4 possible outcomes
Explanation:
Ava flipped a coin 2 times.
Let T represent the coin landing tails up and H represent the coin landing heads up.
When First coin is Tail then second Coin can be Tail or Head
So there are two possibilities (T, H) (T, T)
When First coin is Head then second Coin can be Tail or Head
So there are two possibilities (H, H) (H, T)
When two coins are flipped there are 4 possibilities
(T, H) (T, T) (H, H) (H, T)
