Question

1.Write the expression for pdf of a Poisson and binomial Random variable.

2. Define mean and variance of a random variable.

Answer 1

Step-by-step explanation:

A Random Variable is a variable whose possible values are numerical outcomes of a random experiment. The Mean (Expected Value) is: μ = Σxp. The Variance is: Var(X) = Σx2p − μ2. The Standard Deviation is: σ = √Var(X)

Answer 2

Answer:

1. In probability theory and statistics, the Poisson binomial distribution is the discrete probability distribution of a sum of independent Bernoulli trials that are not necessarily identically distributed. The concept is named after Siméon Denis Poisson.

2.A Random Variable is a variable whose possible values are numerical outcomes of a random experiment. The Mean (Expected Value) is: μ = Σxp. The Variance is: Var(X) = Σx2p − μ2. The Standard Deviation is: σ = √Var(X)
