7th Grade- Theoretical and Experimental Probability

Front

What is probability?

Back

Probability is a measure of how likely an event is to occur, expressed as a number between 0 and 1.

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 outcomes.

Front

What is experimental probability?

Back

Experimental probability is the likelihood of an event based on actual experiments or trials, calculated as the number of times the event occurs divided by the total number of trials.

Front

If a coin is flipped 100 times, how many times would you expect tails to appear?

Back

Approximately 50 times.

Front

What is the probability of choosing a striped marble from a bag containing 2 striped marbles and 3 non-striped marbles?

Back

The probability is 2/5.

Front

How do you calculate the probability of NOT landing on a specific color in a spinner?

Back

Subtract the probability of landing on that color from 1.

Front

What is the theoretical probability of rolling a 1 on a fair six-sided die?

Back

1/6.

Front

If a die is rolled five times and the results are 1, 3, 3, 4, 4, what is the experimental probability of rolling a 1?

Back

1/5.

Front

What is the total number of outcomes when rolling a die?

Back

6.

Front

What is the formula for calculating probability?

Back

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