Theoretical and Experimental Probability

Front

What is Experimental Probability?

Back

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

Front

What is Theoretical Probability?

Back

Theoretical Probability is the probability based on the possible outcomes in a perfect scenario.

In a bag with 4 green marbles, 3 red marbles, 2 blue marbles, and 1 yellow marble, what is the theoretical probability of pulling a blue marble?

Back

2/10 or 1/5

Front

How do you calculate Experimental Probability?

Back

Experimental Probability = (Number of times the event occurs) / (Total number of trials).

Front

What is the formula for Theoretical Probability?

Back

Theoretical Probability = (Number of favorable outcomes) / (Total number of possible outcomes).

If Shannon selects a red jelly bean 11 times out of 33 trials, what is the experimental probability of selecting a red jelly bean?

Back

1/3

Front

What is the probability of not selecting a red jelly bean if the experimental probability of selecting one is 1/4?

Back

3/4

If a die is rolled, what is the theoretical probability of rolling an even number?

Back

3/6 or 1/2.

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.
