The dependent event is (b) Drawing a 2 from a deck of cards not replacing it and then drawing another 2

How to determine the dependent events

From the question, we have the following parameters that can be used in our computation:

The events

Events are considered dependent if the occurrence or outcome of one event affects the occurrence or outcome of the other.

Using the above as a guide, we have the following:

1. Drawing a king from a deck of cards, replacing it, and then drawing another king:

These events are independent because replacing the first king means the deck is back to its original state

2. Drawing a 2 from a deck of cards, not replacing it, and then drawing another 2:

These events are dependent because not replacing the first 2 changes the composition of the deck

3. Rolling a die and getting 6, and then rolling it again and getting 6 again:

These events are independent because each roll is independent of the other.

4. Flipping a coin and getting tails, and then flipping it again and getting tails again:

These events are independent because the outcome each flip is independent of the other.
