Probability Test Review

Front

What is experimental probability?

Back

Experimental probability is the ratio of the number of times an event occurs to the total number of trials conducted.

Front

What is theoretical probability?

Back

Theoretical probability is the likelihood of an event happening based on all possible outcomes, calculated as the number of favorable outcomes divided by the total number of possible outcomes.

Front

How does increasing the number of trials affect experimental probability?

Back

As the number of trials increases, the experimental probability tends to get closer to the theoretical probability.

Front

What is the formula for calculating probability?

Back

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

Front

If a coin is flipped, what is the theoretical probability of getting tails?

Back

The theoretical probability of getting tails when flipping a fair coin is 0.5.

Front

In a group of 15 alligators, if 5 are juveniles, what is the probability of randomly selecting a juvenile?

Back

Probability = 5/15 = 1/3.

Front

What is the probability of selecting a girl from a class of 12 boys and 9 girls?

Back

Probability = 9/(12+9) = 9/21 = 3/7.

Front

If there are 3 students named Stephanie in a class of 20, what is the probability of picking a Stephanie?

Back

Probability = 3/20.

Front

What is the expected experimental probability of landing on Pink after spinning a spinner 2,000 more times if it landed on Pink 15 times out of 25?

Back

The expected experimental probability will increase to 20%.

Front

What does it mean if the experimental probability is different from the theoretical probability?

Back

It indicates that the outcomes of the trials may not perfectly reflect the expected outcomes due to randomness or a limited number of trials.
