The binomial coefficient is the number of ways of picking unordered outcomes from possibilities, also known as a combination or combinatorial number. therefore gives the number of k-subsets possible out of a set of distinct items. For example, The 2-subsets of are the six pairs , , , , , and , so . The number of lattice paths from the origin to a point ) is the binomial coefficient (Hilton and Pedersen 1991).
The number of successes X in n trials of a binomial experiment is called a binomial random variable. The probability distribution of the random variable X is called a binomial distribution, and is given by the formula: `P(X)=C_x^n p^x q^(n-x)`. where. n = the number of trials. x = 0, 1, 2, ...n.p = the probability of success in a single trial. q = the probability of failure in a single trial. (i.e. q = 1 â p). `C_x^n` is a combination. P (X) gives the probability of successes in n binomial trials. = the probability of success in a single trial. q = the probability of failure in a single trial. (i.e. q = 1 â p). `C_x^n` is a combination. P (X) gives the probability of successes in n binomial trials.
