Cara and her brother take a numbered spinner from a board game and use it to determine

who will get to play with their new puppy first. Cara spins, and then her brother does.

Are these two events dependent or independent?

They are dependent events because if cara spins it and it lands on her she gets to play with the puppy, But if she misses it and her brother spins and it lands on him he gets to play with the puppy.

Short answer: the event is dependent because the outcome of the first spin effects the brother outcome
