Alberto conducted an experiment by rolling a fair six-sided number cube 60 times. He rolled a 2 fifteen times. Which statement about rolling a 2 in Alberto's experiment is correct?

The experimental probability of rolling a 2 is 1/3 and the theoretical probability of rolling a 2 is 1/4.

The experimental probability of rolling a 2 is 1/4 and the theoretical probability of rolling a 2 is 1/3.

The experimental probability of rolling a 2 is 1/4 and the theoretical probability of rolling a 2 is 1/6.

The experimental probability of rolling a 2 is 1/6 and the theoretical probability of rolling a 2 is 1/4

The experimental probability of rolling a 2 is 1/4 and the theoretical probability of rolling a 2 is 1/6. There are six numbers on the cube so the probability of rolling a 2 is 1 out of 6 possible outcomes. In the experiment, the number 2 appeared 15 out of 60 rolls, or 1/4.
