Theoretical vs. experimental probability

Front

What is Experimental Probability?

Back

Experimental Probability is what actually happens in an experiment.

Front

What is Theoretical Probability?

Back

Theoretical Probability is what should happen based on possible outcomes.

Front

If a bag contains 10 jelly beans (3 red, 2 blue, 5 green), what is the theoretical probability of picking a red jelly bean?

Back

Theoretical Probability of red = Number of red jelly beans / Total jelly beans = 3/10.

What is the formula for Experimental Probability?

Back

Experimental Probability = Number of times an event occurs / Total number of trials.

Front

If a spinner is spun 20 times and lands on 'A' 5 times, what is the experimental probability of landing on 'A'?

Back

Experimental Probability of 'A' = 5/20 = 1/4.

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

Front

What does it mean if an experimental probability is close to the theoretical probability?

Back

It means that the experiment is likely reflecting the expected outcomes accurately.

Front

If a coin is flipped 50 times and lands on heads 30 times, what is the experimental probability of getting heads?

Back

Experimental Probability of heads = 30/50 = 3/5.
