Answer:

MARK ME AS BRAINLIEST ANSWER.

Step-by-step explanation:

The probability distribution of a binomial random variable is called a binomial distribution. ... The mean of the distribution (μx) is equal to n * P . The variance (σ2x) is n * P * ( 1 - P ).

Answer 2

Suppose we flip a coin two times 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 distribution is presented below.The binomial distribution has the following properties:

The mean of the distribution (μx) is equal to n * P .

The binomial distribution has the following properties:The mean of the distribution (μx) is equal to n * P .The variance (σ2x) is n * P * ( 1 - P ).
