The Poisson probability distribution‚ named after the French mathematician Siméon-Denis. Poisson is another important probability distribution of a discrete random variable that has a large number of applications. Suppose a washing machine in a Laundromat breaks down an average of three times a month. We may want to find the probability of exactly two breakdowns during the next month. This is an example of a Poisson probability distribution problem. Each breakdown is called an occurrence in Poisson

During the Republican National Convention on August 19‚ 1992‚ Mary Fisher‚ a woman with AIDS‚ delivered the speech “A Whisper of AIDS” to shed light on the spread of HIV and AIDS‚ an issue that was seemingly ignored at the time. According to the Centers for Disease Control and Prevention‚ “the number of perinatally acquired AIDS cases peaked in 1992‚” reaching 901 cases. Before delivering the speech‚ Fisher’s main recognitions were for being a movie producer and an assistant to President Gerald R

In order for patrol distribution to be effective‚ it must revolve around the goal of trying to satisfy the vast majority of citizens’ concerns within a jurisdiction (Fritsch et al.‚ 2008). Patrol allocation should be taken into consideration in order to effectively distribute the patrol. Depending on the size of a police department and its jurisdiction‚ patrol allocation can help distribute the patrol by dividing the patrol jurisdiction into different areas and assigning officers to patrol some or

Essay Title: Describe and explain the population distribution of Brazil. Population distribution means the pattern of where people live. The world’s population distribution is very uneven. Places which are sparsely populated contain few people and places which are densely populated contain many people. Sparsely populated places tend to be difficult places to live. These are usually places with hostile environments e.g. Antarctica. Places which are densely populated are habitable environments e.g

Macroeconomics LP4 Assignment A price ceiling is a sort of price control governments have imposed to control the price when the price is higher than it should be. Sellers try to sell more of their product because the price is high. But buyers do not want to buy at that price. Price ceilings commonly lead to shortages and are typically associated with long lines. When a new toy or video game comes out there is usually some kind of wait‚ whether in line or on a waiting list. When “tickle me
