The table shows the results of 60 rolls of a fair number cube numbered 1 to 6. Which statement best describes the experimental and theoretical probability of rolling a 3?

The news uses a weather simulator to predict the theoretical probability of precipitation. The computer simulation predicted that theoretically, precipitation should occur in 60% of the month of January. Which statement best compares the theoretical and experimental probability of precipitation in January?

• The theoretical probability and experimental probability of precipitation is equal.

• The theoretical is less than the experimental probability of precipitiation.

• The theoretical is greater than the experimental probability of precipitation.

• The data given is not enough to compare the experimental and the theoretical probability of precipitation.

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 best describes dependent events?

• Randomly selecting one tile from Bag A, replacing the tile, then randomly selecting another tile from Bag A.

• Randomly selecting one tile from Bag B, not replacing the tile, then randomly selecting another tile from Bag B.

• Randomly selecting one tile from Bag A, replacing the tile, then randomly selecting another tile from Bag B.

• Randomly selecting one tile from Bag B, not replacing the tile, then randomly selecting another tile from Bag A.

A bag contains 3 blue marbles and 2 yellow marbles. An example of independent events using this bag of marbles is randomly selecting a blue marble, _____ and then randomly selecting another blue marble.
