Comparing Experimental and Theoretical Probability

Front

What is THEORETICAL PROBABILITY?

Back

Theoretical Probability is what SHOULD happen in an experiment.

Front

What is EXPERIMENTAL PROBABILITY?

Back

Experimental Probability is what DID happen during the experiment.

Front

Determine the type of probability: The probability of flipping tails is 1/2, or 50%, since the sides of a coin have 1 tails and 1 heads.

Back

Theoretical Probability.

Front

If the spinner was spun 50 times and landed on 11 fifteen times, what is the theoretical probability of landing on 11?

Back

The theoretical probability of landing on 11 is 12.5%.

Front

If the spinner was spun 50 times and landed on 11 fifteen times, what is the experimental probability of landing on 11?

Back

The experimental probability of landing on 11 is 30%.

Front

Determine the type of probability: Jane rolled a regular number cube 25 times. She rolled an EVEN number 11 times. What is the probability of EVEN numbers?

Back

The experimental probability of rolling an EVEN number is 44%.

Front

What is the formula for calculating theoretical probability?

Back

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

Front

What is the formula for calculating experimental probability?

Back

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

Front

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

Back

The theoretical probability of rolling a 3 is 1/6.

Front

If a coin is flipped 100 times and lands on heads 45 times, what is the experimental probability of landing on heads?

Back

The experimental probability of landing on heads is 45/100 or 45%.
