A spinner with four equal-size sections marked X, Y, Z, and Q is spun 100 times. The spinner lands on X 20 times. Which comparison of the experimental probability and theoretical probability of the spinner landing on X is valid?

• the experimental probability is greater than the theoretical probability

• the experimental probability is less than the theoretical probability

• the experimental probability is equal to the theoretical probability
