Enter the number of possible outcomes and number of events occurred* *in the conditional probability calculator** **below to find the probability.

The probability equation can be expressed as:

*P(A) = n(A)/n(S)*

Where,

** P(A) **refers to the probability of event

** n(A) **is the number of possible outcomes, and

** n(S) **is the number of events occurred.

To calculate the *probability of event that does not occur,* use the below equation.

*P(A') = 1 - **P(A)*

To calculate the probability of two events ** a** and

*P(A and B) = A(A) × P(B)*

Calculating probability was never so simple. Thanks to the cumulative probability calculator**, **probability of a and b** **can now be calculated at one click.

Let’s go through some of the important concepts such as probability definition, formula of probability, and how to find probability without using chance calculator.

Probability tells us the likelihood of an event to occur.

According to towards data science,

Probability is the measure of the likelihood that an event will occur in a random experiment. Probability is calculated as a number between 0 and 1. 1 indicates certainty and 0 indicates impossibility. The greater the probability of an event, the more likely it is that the event will happen.

For example, If a coin is flipped, there are equal chances that a head or tail will show up. In this case, the probability is 0.5 or fifty percent.

First of all, the probability distribution calculator** **is the best way to find the probability in less time than any other method. If you want to learn the manual method, here are the steps to evaluate the possibilities of an event to occur.

**Example:**

If there are ** 8 **candies in a jar, from which

**Solution:**

**Step 1: **We will calculate the probability of coconut candy. So,

*n(A) = 3*

*n(S) = 8*

**Step 2: **Let’s use the formula to calculate probability.

*P(A) = n(A)/n(S)*

*P(A) = 3/8*

** P(A) = 0.375 **or

**Step 3: **Calculate the probability of event that does not occur by using its formula given above.

*P(A') = 1 - **P(A)*

*P(A') = 1 - **0.375*

*P(A') = 0.625 ***or 62.5%**

Probability can be calculated by dividing the total number of possible outcomes with the number of events occurred.

*P(A) = n(A)/n(S)*

The probability of A or B is the probability of two disjoint events. It can be calculated by adding the probability of both events.

*P(A or B) = P(A) + p(B)*
