A number cube is rolled 20 times. The results are shown. Choose the statement that is true about the experimental and theoretical probability of the situation.

• 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 50% and the theoretical probability of rolling 6 is 25%

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 1/8 while the experimental probability of landing on 11 is 30%

• The experimental probability of landing on 11 is 25% while the theoretical probability of landing on 11 is 30%

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