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

• 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.
