Introduction to solve Poisson binomial distribution:
Siméon-Denis Poisson introduces the Poisson binomial distribution. Poisson binomial distribution is one of the statistics discrete probability distribution.. It used to find the possibility of an event in a given rate of value (λ). A poison experiment (x0 refers the random variable. In this article we shall discuss about to solve Poisson binomial distribution example problem. Here we are going to solve the problem with detailed solutions.
Solve Poisson Binomial Distribution Example Problem:
Example:
In an office there are 4 staffs absent today. Find the possibilities for exactly 6 staff to be taking leave on tomorrow.
Solution:
Step1:
Find e-λ.
Where, λ=4 and e=2.718
e-λ = (2.718)-4 = 1/54.575510850576
= 0.0183232366
Step2:
Find λx.
Where, λ=4 and x=6.
λx = 46 = 4096.
Step3:
Find f(x).
f(x) = e-λλx / x!
f(6) = (0.0183232366)(4096) / 6! .
=75.05195 /720
= 0.1042388.
Hence there are 10% possibilities for 6 staffs to be taking leave of an office on tomorrow.
Example:
In an office there are 5 staffs absent today. Find the possibilities for exactly 7 staff to be taking leave on tomorrow.
Solution:
Step1:
Find e-λ.
Where, λ=5 and e=2.718
e-λ = (2.718)-5 = 1/148.3362
= 0.006741
Step2:
Find λx.
Where, λ=5 and x=7.
λx = 57 = 78125.
Step3:
Find f(x).
f(x) = e-λλx / x!
f(7) = (0. 006741)(78125) / 7! .
= 526.67521 /5040
= 0.104499.
Hence there are 0.10% possibilities for 7 staffs to be taking leave of an office on tomorrow.
Example:
In an office 2 clients visit today. Find the possibilities for exactly 4 clients to be visit on tomorrow.
Solution:
Step1:
Find e-λ.
Where, λ=2 and e=2.718e-λ = (2.718)-2 = 1/7.387524
= 0.135633
Step2:
Find λx.
Where, λ=2 and x=4.
λx = 24 = 16.
Step3:
Find f(x).
f(x) = e-λλx / x!
f(4) = (0. 135633)(16) / 4! .
= 2.16581/24
= 0.09024.
Hence there are 9% possibilities for 4 clients to be visit an office on tomorrow.I have recently faced lot of problem while learning how to find the least common denominator, But thank to online resources of math which helped me to learn myself easily on net.
