Theoretical and Experimental Probability

Front

What is Experimental Probability?

Back

Experimental Probability is the probability based on the data from an experiment.

Front

How many times was the number cube rolled in the bar graph?

Back

The number cube was rolled 50 times.

Front

If the arrow is spun 15 times and landed on section Q 4 times, what is the experimental probability of landing on Q?

Back

The experimental probability of landing on Q is 4/15.

Front

What is the theoretical probability of tossing a number cube and it landing on an even number?

Back

The theoretical probability of landing on an even number is 3/6 or 1/2.

Front

If Neil tossed a 6-sided die 90 times and the experimental probability of rolling a 1 is 13/90, how many times did he roll a 1?

Back

Neil rolled a 1 a total of 13 times.

Front

What is the difference between theoretical and experimental probability?

Back

Theoretical probability is based on expected outcomes, while experimental probability is based on actual results from an experiment.

Front

What is the formula for calculating experimental probability?

Back

Experimental Probability = (Number of successful outcomes) / (Total number of trials).

Front

If a number cube is rolled, what is the theoretical probability of rolling a number greater than 4?

Back

The theoretical probability of rolling a number greater than 4 is 2/6 or 1/3.

Front

What does a bar graph represent in probability experiments?

Back

A bar graph visually represents the frequency of outcomes from probability experiments.

Front

If an experiment is conducted 100 times and an event occurs 25 times, what is the experimental probability of that event?

Back

The experimental probability is 25/100 or 1/4.
