There is a 90 percent probability that the increase will be between 6.3 and 13.3 degrees (F). [ Update – May 22, 3:00 p.m.: To understand why such minor gaffes can lead to major problems, read Judy ...

I was preparing for my early morning class back in January 2025 when I received a notice regarding an asteroid called 2024 YR4. It said the probability it could hit Earth was unusually high. As ...

A simple example is the toss of a coin. The probability is 1/2 (or a 50% chance) of either "heads" or "tails". Statistics is the study of the collection, analysis, interpretation, presentation ...

Probability is used in everyday life. For example, in medicine in determining the chance of a drug working and by insurance companies in determining the cost of car insurance for different age groups.

Bayesian probability is the basis of all our beliefs, and to a large extent our success in life is related to how nimble we are in keeping up with the slippery beast of probability. More ...

They split the problem up into small, manageable steps. Instead of trying to solve for the entire probability distribution in one go, they focused on only a small slice of the moments. For example, to ...

For example, suppose you wanted to know the probability that the S&P 500 would return a positive percentage this year, given initial gross domestic product (GDP) figures.

An example would be I rolled the dice three times and got 12 three times, for a statistical probability of 12/12 or 100%. This calculation demonstrates the flaw of empirical probability. Examples ...

A mysterious math problem from Science Buddies. If you survey a random group of just 23 people there is actually about a 50–50 chance that two of them will have the same birthday.
