Final Review Before Unit 5 Test

Choose the statement that is true about the experimental and theoretical probability of rolling a number cube 20 times.

• The experimental probability of rolling 3 is 16.6% and the theoretical probability is 15%

• The experimental probability of rolling 3 is 15% and the theoretical probability is 16.6%

• The experimental probability of rolling 1 is greater than the theoretical probability

• The experimental probability of rolling 6 is 16.6% and the theoretical probability of rolling 6 is 25%

The spinner was spun 30 times and landed on blue 12 times. What was the experimental probability of the spinner landing on colors that were not blue?

• 2/5

• 3/5

• 4/5

• 1/5

• The more times the coin is tossed, the closer the experimental probability will get to the theoretical probability

• The theoretical probability is less than the experimental probability of landing on tails.

• The theoretical probability of landing on tails is 1/2 and the experimental probability of landing on tails is 19/40

• The theoretical probability is the same as the experimental probability of landing on tails.

Janice reached into Molly's sack of Marbles 10 times and picked a green Marble 3 times. Choose each statement that is true.

• The experimental probability of Janice picking a green marble was greater than the theoretical probability of Janice picking a green marble

• The theoretical probability of picking a blue marble was greater than the theoretical probability of picking a green marble

• The experimental probability of Janice picking a green marble was greater than the theoretical probability of picking a purple marble

• The more Janice picked a green marble from the bag, the closer the experimental probability will get to the theoretical probability.
