3-19-20 Comparing Experimental and Theoretical Probability

Front

What is Experimental Probability?

Back

Experimental Probability is what DID happen during the experiment.

Front

What is Theoretical Probability?

Back

Theoretical Probability is what SHOULD happen in an experiment based on the possible outcomes.

Front

If a fair number cube is rolled 6 times and the number 4 appears 2 times, what is the experimental probability of rolling a 4?

Back

The experimental probability of rolling a 4 is 2/6 or 1/3.

Front

What is the theoretical probability of rolling an even number on a fair number cube?

Back

The theoretical probability of rolling an even number (2, 4, or 6) is 3/6 or 1/2.

Front

If Jane rolled a number cube 25 times and got an even number 11 times, what is the experimental probability of rolling an even number?

Back

The experimental probability of rolling an even number is 11/25 or 44%.

Front

What is the theoretical probability of flipping heads on a fair coin?

Back

The theoretical probability of flipping heads is 1/2 or 50%.

Front

If a number cube is rolled 20 times and the number 3 appears 3 times, what is the experimental probability of rolling a 3?

Back

The experimental probability of rolling a 3 is 3/20 or 15%.

Front

What is the difference between experimental and theoretical probability?

Back

Experimental probability is based on actual experiments, while theoretical probability is based on expected outcomes.

Front

If the theoretical probability of an event is 1/6, what is the expected frequency of that event in 60 trials?

Back

The expected frequency is 10 times (60 * 1/6).

Front

What is the experimental probability of rolling a number less than 3 if a number cube is rolled 30 times and the result is 8 times?

Back

The experimental probability is 8/30 or 4/15.
