can be used to develop estimates about how many operations a computer algorithm will require.

Combinatorics methods

can be used to count possible outcomes in a uniform probability experiment.

Algorithm analysis

is an important part of computational complexity theory, which provides theoretical estimation for the required resources of an algorithm to solve a specific computational problem.

computational complexity theory

provides theoretical estimation for the required resources of an algorithm to solve a specific computational problem.

Discrete probability distribution

is a type of probability distribution that shows all possible values of a discrete random variable along with the associated probabilities.

Discrete probability distribution

gives the likelihood of occurrence of each possible value of a discrete random variable.

probability distribution

is the mathematical function that gives the probabilities of occurrence of possible outcomes for an experiment.

probability distribution

It is a mathematical description of a random phenomenon in terms of its sample space and the probabilities of events

recurrence relation

is an equation which represents a sequence based on some rule.

recurrence relation

It helps in finding the subsequent term (next term) dependent upon the preceding term (previous term).

recurrence relation

If we know the previous term in a given series, then we can easily determine the next term.

standard pattern

• Since a _____ is developed now, we can find the set of new terms.

  • This is also applicable for arithmetic and geometric sequence.
