Step-by-step explanation: The first option is
A: A bird lands on your head.
B: The bird lays an egg.
Since there is no connection between statements A and B, so these are independent events.
The second option is
A: A mosquito lands on your arm.

* A: A bird lands on your head.
B: The bird lays an egg.
* A: A green ball is drawn from a box with five balls and placed next to the box.
B: A red ball is drawn next and placed next to the green one.
