3) Greta has 2 bags of tiles
that are all the same size and
shape.

•Bag A has 1 blue tile
and 3 green tiles

•Bag B has 2 yellow
tiles and 4 black tiles

Which of these bests
describes dependent events?

a) Selecting a tile from
Bag B, replacing it,
then selecting a tile
from Bag B

b) Selecting a tile from
Bag B, not replacing it,
then selecting another
tile from Bag B.

B would be a *dependent* event, and A would be an *independent* event.

Step-by-step explanation:

Independent events are separate events where the outcome in either event does not affect the other's probability. The opposite, where the outcome of the one event affects the other's probably, is dependent.

For Option A, taking a tile out and then replacing it does not affect the probability that the same tile will be picked for the 2nd picking.

For Option B, taking a tile out of the bag and then picking another tile are 2 separate events and both have different probabilities for picking identical tiles.

Therefore, Option B is dependent and Option A is independent.
