How to Use the Event Probability Calculator?

The procedure to use the event probability calculator is as follows:

Step 1: Enter the number of favorable outcomes of the event A and possible outcomes in the respective input field

Step 2: Now click the button “Solve” to get the result of P(A) and P(A’)

Step 3: Finally, the probability of occurring and not occurring of the event A will be displayed in the output field

What is Meant by Event in Probability?

In probability, an event can be defined as the set of outcomes of an experiment. Event is the subset of sample space of the random experiment. Probability of an event is the ratio of the number of outcomes favorable to the event to the total number of possible outcomes of the experiment. We can observe different types of events in probability. The formula to find the probability of event E is given by:

P(E) = n(E)/ n(S)

Here,

n(E) = Number outcomes favorable to event E

n(S) = Total number of outcomes (i.e. total number of elements in the sample space)
