What is Probability?
Probability is a branch of mathematics that deals with the likelihood of a given event happening. It's a measure of how likely an event is to occur, expressed as a number between 0 and 1, or as a percentage between 0% and 100%.
A probability of 0 means the event will not occur, while a probability of 1 means the event will definitely occur.

Functionality
Our Probability Calculator performs several critical functions:
- Single Event Probability: Calculates the likelihood of a single event occurring.
- Combined Probability of Multiple Events: Computes the probability of multiple events happening together, whether they are independent or dependent.
- Conditional Probability: Determines the probability of an event occurring given that another event has occurred.
- Complementary Probability: Calculates the probability of an event not occurring.
What is a 3% Chance?
A 3% chance refers to the probability of an event occurring being 0.03 or 3%. This means that out of 100 trials, the event is expected to occur approximately 3 times.
It indicates a relatively low likelihood but is not impossible.
How Probability Works
Probability is calculated using the ratio of favorable outcomes to the total number of possible outcomes. The basic formula is:
P(A)= Number of favorable outcomes /Total number of possible outcomes
For example, if you roll a six-sided die, the probability of rolling a 4 is 1/6, as there is only one favorable outcome (rolling a 4) out of six possible outcomes.

Probability Calculator for Multiple Events
Probability Calculator for 4 Events
When dealing with four events, our calculator allows you to input the probability for each event and determine the overall probability based on whether the events are independent or dependent. The calculation for four independent events is:
P(A and B and C and D)=P(A)×P(B)×P(C)×P(D)
What Is 25% as a Probability?
A percentage can be easily converted to a probability by expressing it as a fraction or a decimal.
When we say 25%, it means 25 out of 100, which can be written as the fraction 25/100. Simplifying this fraction, we get 1/4. Alternatively, 25% can also be expressed as the decimal 0.25.
In probability terms, 25% represents a one-in-four chance of an event occurring. For example, if you draw a card from a deck with four cards marked A, B, C, and D, the probability of drawing card A is 25%. Thus, 25% probability indicates that the likelihood of the event happening is one out of four possible outcomes.
Probability Calculator for 5 Events
For five events, the process is similar, but with an added level of complexity. The formula for independent events is:
P(A and B and C and D and E)=P(A)×P(B)×P(C)×P(D)×P(E)
Our calculator handles this complexity effortlessly, providing accurate results with ease.
