The probability is a number between 0 and 1; the larger the probability, the more likely the desired outcome is to occur. For example, tossing a coin twice will yield "head-head", "head-tail", "tail …

How likely something is to happen. Many events can't be predicted with total certainty. The best we can say is how likely they are to happen, using the idea of probability. When a coin is …

Explore what probability means and why it's useful. Probability is simply how likely something is to happen. Whenever we’re unsure about the outcome of an event, we can talk about the …

Probability is all about how likely is an event to happen. For a random experiment with sample space S, the probability of happening of an event A is calculated by the probability formula n …

The probability of a specified event is the chance or likelihood that it will occur.

We will answer these questions here along with some useful properties of probability. Probability is a numerical measure of the likelihood that a specific event will occur.

Dec 6, 2025 · The probability of an event E, denoted by P (E), is a number between 0 and 1 that represents the likelihood of E occurring. If P (E) = 0, the event E is impossible.

Probability of a Normal Distribution Use the calculator below to find the area P shown in the normal distribution, as well as the confidence intervals for a range of confidence levels.
