Calculation of Combination Probability
Why do we use combination probability?
We use combination probability to calculate the possible outcome of an event where the order of outcome does not matter.
How is the probability of a combination is related to the probabilities of its components?
Here components refer to the individual events of a combination. The probability of a combination = The product of the probabilities of the individual components.
What is the formula of Combination?
nCr = n!/(n-r)!r!
where
- n = total number items,
- r = number of items to be chosen at a time.
Can combinations have repetition?
In permutation, order matters and repetition is not allowed whereas in combination, order of outcomes does not matter, but the repetition is allowed.
What are the three rules of probability?
The three rules of probability are:
- multiplication rule
- addition rule
- complement rule
How To Calculate Probability using Combination
Combination probability is a mathematical method that involves the process of combination in determining the number of favorable outcomes of an event. We use combinations in probability problems to determine a sequence of outcomes where the order of the outcomes does not matter. Understanding how to calculate combination probability can be a useful mathematical skill in the field of math and science.
In this article, we will discuss in detail the definitions of combination and probability and how to calculate combination probability with solved examples.
