• Question 3
300 seconds Q.

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%

• Question 4

• Question 6
300 seconds Q.

If the spinner was spun 50 times and landed on 11 fifteen times, which statement is true?

The experimental probability of landing on 11 is 1/8 while the theoretical probability of landing on 11 is 3/10

The theoretical probability of landing on 11 is 12.5% while the experimental probability of landing on 11 is 30%

The experimental probability of landing on 11 is less than the theoretical probability of landing on 11

The theoretical probability of landing on 11 is equal to the experimental probability of landing on 11

• Question 9
300 seconds Q.

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.

• Question 10

• Question 11
300 seconds Q.

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.
