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 occurring based on all possible outcomes, calculated as the number of favorable outcomes divided by the total number of outcomes.

How do you calculate the probability of rolling greater than a 1 on a single die?

Back

The probability is calculated as the number of favorable outcomes (2, 3, 4, 5, 6) over the total outcomes (1, 2, 3, 4, 5, 6), which is 5/6.

What does a probability of 0 mean?

Back

A probability of 0 means that the event cannot occur.

Front

If a spinner is spun 50 times and lands on a number 15 times, what is the experimental probability of that number?

Back

The experimental probability is 15/50, which simplifies to 3/10.

What is the relationship between experimental and theoretical probability?

Back

Experimental probability is based on actual trials, while theoretical probability is based on expected outcomes. They can differ due to chance.

Front

What is an unlikely event in probability?

Back

An unlikely event is one that has a probability close to 0.
