Classifying Theoretical vs Experimental Probability

What is theoretical probability based on?

• Number of desired outcomes over total possible outcomes

• Results of an experiment

• Past experiences

• Guesswork

Why is it important to understand both theoretical and experimental probability?

• To compare predictions with actual outcomes

• To make experiments unnecessary

• To accurately predict future events

• To improve guessing skills

What must occur before you can calculate experimental probability?

• A theoretical prediction

• A hypothesis

• An actual experiment

• A mathematical formula

How is experimental probability calculated?

• Using a probability calculator

• Predictions before an experiment

• Successes in the experiment divided by number of trials

• Desired outcomes divided by total outcomes

What is the experimental probability based on?

• Predictions made before the experiment

• A random guess

• Outcomes from an actual experiment

• Theoretical calculations

In a coin toss, what is the theoretical probability of getting heads?

• 1/3

• 3/4

• 1/4

• 1/2

How can you compare experimental and theoretical probabilities?

• By asking an expert

• By conducting more experiments

• By guessing and checking

• By finding a common denominator and comparing fractions

What indicates a successful experiment in terms of probability?

• When you can repeat the experiment with the same results

• When experimental probability is higher than theoretical

• When theoretical and experimental probabilities are exactly the same

• When theoretical probability is higher than experimental

What does finding a common denominator help with in probability?

• Predicting outcomes without an experiment

• Simplifying fractions

• Calculating experimental probability

• Comparing different probabilities
