Binomial Distribu�on A binomial random variable is the number of successes x in n repeated trials of a binomial experiment. The probability distribu�on of a binomial random variable is called a binomial distribu�on.
Suppose we flip a coin two �mes and count the number of heads (successes). The binomial random variable is the number of heads, which can take on values of 0, 1, or 2. The binomial distribu�on is presented below.
Number of heads Probability 0 0. 1 0. 2 0. The binomial distribu�on has the following proper�es:
The mean of the distribu�on (μx) is equal to n * P. The variance (σ2x) is n * P * ( 1 - P ). The standard devia�on (σx) is sqrt[ n * P * ( 1 - P ) ].
