Zamari has a spinner with equal sections red, blue, yellow, green, and orange. He says that the theoretical probability of the spinner landing on blue is
. He then spins the spinner 10 times and it lands on blue 4 times. He calculates the experimental probability to be
.
Which of the following best describes the discrepancy between Zamari's theoretical and experimental probabilities?

A Zamari only spun the spinner 10 times. If he increases the number of spins, the experimental probability should get closer to the theoretical probability.Zamari only spun the spinner 10 times.

B Zamari calculated the theoretical probability incorrectly. The theoretical probability is also

C The experimental probability can never be exactly
, but it's a good enough approximation.The experimental probability can never be exactly 1 fifth , but it's a good enough approximation.
D The spinner's sections are probably not truly equal. The blue section is likely bigger than
