Question

A paper cup is dropped and its landing position is recorded. The cup can land on the side, on the open end, or on the closed end. The results of 20 trials are shown in the table below. Based on the table, which of the following best compares the experimental probability of the cup landing on its open end with the experimental probability of the cup landing on its closed end? A. The probabilities are equal. B. The probability of landing on the open end is greater.

C. The probability of landing on the closed end is greater.
D. No conclusion can be made.

Answer 1

A. The probabilities are equal.

Explanation:

HOPE THIS HELPS! :)

taking the test :))))))))

Answer 2

General Idea:

Experimental probability refers to the probability of an even occurring when an experiment was conducted and data was produced detailing the number of times an even occurred. Experimental probability is found by repeating an experiment and observing the outcomes.

P(event) = Number of times event occur/Total number of trials

Applying the concept:

The experimental probability of the cup landing on its open end =
`(5)/(20)=(1)/(4)`

The experimental probability of cup landing on its closed end =
`(5)/(20)=(1)/(4)`

Conclusion:

The statement which best compares the experimental probability of the cup landing on its open end with the experimental probability of the cup landing on its closed end is option A.

The probabilities are equal.
