Experimental and Theoretical Probability

Front

What is Experimental Probability?

Back

Experimental Probability is what actually happens based on the results of an experiment.

Front

What is Theoretical Probability?

Back

Theoretical Probability is the probability of an event occurring based on the possible outcomes, assuming all outcomes are equally likely.

Front

What is the formula for calculating Theoretical Probability?

Back

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

Front

If a die is rolled, what is the theoretical probability of rolling a 3?

Back

1/6 or approximately 16.67%.

Front

What is the theoretical probability of rolling an even number on a standard die?

Back

3/6 or 1/2 (50%). The even numbers are 2, 4, and 6.

Front

What is the theoretical probability of picking a vowel from the letters A, B, C, D, and E?

Back

2/5. The vowels are A and E.

Front

What is the probability of landing on a 3 in a spinner divided into 4 equal parts?

Back

1/4 or 25%.

Front

What does it mean if an event has a probability of 0?

Back

It means the event is impossible and will not occur.

Front

What does it mean if an event has a probability of 1?

Back

It means the event is certain to occur.

Front

How do you calculate Experimental Probability?

Back

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