To verify that the … There are three major distributions associated, the Bernoulli distribution, the binomial distribution and the geometric distribution. • Bernoulli distribution: ber(p) , is used to model an experiment with only two possible outcomes. The two outcomes are often encoded as 1 and 0. p X ( x ) = { p , if x is 1 1 − p , if x is 0 {\displaystyle p_{X}(x)={\begin{cases}p,&{\text{if }}x…
