What is the probability of an event?
The probability is the measure of the likelihood of an event to happen. It measures the certainty of the event. The formula for probability is given by; P (E) = Number of Favourable Outcomes/Number of total outcomes. P (E) = n (E)/n (S) Here, n (E) = Number of event favourable to event E. n (S) = Total number of outcomes. Probability Class 9.
Probability is simply how likely something is to happen. Whenever we’re unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are. The analysis of events governed by probability is called statistics.

- Yes you can multiply probabilities with fractions that are equal to one. We usually want the fraction in the simpliest form though.

What is the Meaning of Probability in Statistics? Probability is a branch of math which deals with finding out the likelihood of the occurrence of an event. Probability measures the chance of an event happening and is equal to the number of favorable events divided by the total number of events.
Learn the basic concept of probability as the measure of the likelihood of an event to occur. Find out the formulas, types, examples and solved problems of probability in maths.
Probability is the branch of mathematics concerning events and numerical descriptions of how likely they are to occur. The probability of an event is a number between 0 and 1; the larger the probability, the more likely an event is to occur. A simple example is the tossing of a fair (unbiased) coin. Since the coin is fair, the two outcomes ...
