Question

luis rolled a number cube 60 times. he rolled the number 6 four times. which is most likely the cause of the discrepancy between luis’s experimental outcome and the predicted outcome?
options:

• he did not perform enough trials.
• he performed too many trials.
• he needs to add the number 6 to the number of times it occurred.
• he needs to subtract the experimental outcome from the predicted outcome.

Explanation:

When dealing with probability experiments (like rolling a number cube), the experimental outcome gets closer to the predicted (theoretical) outcome as the number of trials increases. Rolling a cube 60 times is a relatively small number of trials, so the experimental outcome (rolling a 6 four times) can differ from the predicted outcome. Performing too few trials is a common reason for such a discrepancy. The other options are illogical: adding or subtracting the number of times 6 occurred with 6 doesn't address the discrepancy, and 60 trials isn't "too many" (more trials usually improve accuracy).

Answer:

A. He did not perform enough trials.
