Answer:

First one: Independent

Second one: Independent

Third one: Independent

Step-by-step explanation:

This is an example to prove my answers.

Independent: An event is independent if the outcome of one event doesn't effect the outcome of the other event.

Not independent : An event is Not independent if the outcome of one event effect the outcome of other event.

1. A jar contains twenty coins. Two coins are picked randomly without replacement.

Not Independent because if coins are not replaced the outcome of next event will be effected.

2. A coin is flipped three times.

Independent because when a coin is flipped once its outcome doesn't effect the outcome of the coin flipped again

3. A bag contains 5 red balls and 3 green balls. A red ball is chosen followed by a green ball without replacement.

Not Independent because if balls are not replaced the outcome of next event will be effected.

4. A spinner contains 3 equal sectors labeled A, B and C. The spinner is spun twice.

Independent because when the spinner is spuned once its outcome doesn't effect the outcome of the spinner spun again

Answer:

The answers are dependent, independent, and independent.

Step-by-step explanation:

1. It is dependent because the second selection is influenced by the first selection; there are less coins (1 less).

2. It is independent because the four spins aren't influenced by each other.

3. It is independent because the three spins aren't influenced by each other, also since all of the sections are equally sized.
