<span>The poison distribution can be used to approximate the binomial distribution when the sample size n is large. This is then calculated using the formula P(X) = e^-(np) *(np)^x substituting X= 3 P(3)= e^-(430*1.5/100) * (430*1.5/100)^3 P(3)= 0.00158*268.3 P(3) = 0.42 P(3) = 0.0042% P= probability of X occurring given n and p n= sample size p= true probability e= exponential constant ~2.718 X=number of sample successes</span>

The solution for the problem using binomial distribution:
Given:
p = 1.5% or 0.015 
n = 430
Mean = lambda = m = np = 430*0.015 = 6.45 According to Poisson distribution:
P(x) = e^-(np) *(np) ^x Where:
P is the probability of x
n is the sample size
e is the exponential constant
P(3)= e^-(430*1.5/100) * (430*1.5/100)^3 
P(3)= 0.00158* 268.3336125
P(3) = 0.4240%

effect of full-service partnerships on homelessness, use and costs of mental health services, and quality of life among adults w
leonid [27]

Chronically homeless adults with severe mental illness are heavy users of costly inpatient and emergency psychiatric services. Full-service partnerships (FSPs) provide housing and engage clients in treatment.

A quasi-experimental, difference-in-difference design with a propensity score-matched control group was used to compare mental health service use and costs of FSP with public mental health services.

"Homeless individuals may spend years or even decades living on the streets and in shelters, cycling through emergency departments, inpatient and cri-sis facilities, jails, and mental health and substance use programs. Traditional housing placements often involve segregated and programs typically require individuals to transition from more to less restrictive living situations."

antiseptic1488 [7]
The most important function in the first few seconds or a television commercial is to grab the viewers attention. 

Why? Because if the person thinks the commercial is boring they're gonna go get a snack or skip channels, basically, commercials are so common no one wants to watch a boring one.

Think about the Super Bowl commercials. They’re so well made that people will go back to watch them later. That’s because they are very interesting. People like to watch interesting things.

Three year old Trevor is spending time with his Grandpa while his Dad is at work. Every morning his Dad stops by a local coffee
Vikentia [17]

Answer:

The best answer to the question: What part of Piaget´s theory is Trevor demonstrating, would be: symbolic thinking.

Explanation:

The development of cognitive capacities in both children and adults is a very interesting topic. How children think, how they reason and get to know the world and make sense of it is a topic that has been handled by several experts in psychology, but none as much as Jean Piaget, whose theories of child cognitive development have shaped up until now a lot of what we know about childhood development. In the case of Trevor, the three year old who is associating the action of going to work for his father, with going to the coffee shop, and thus ends up with the question if his father´s office is at the coffee shop, the part of Paiget´s theory that applies is symbolic thinking. Trevor has associated two concepts: his father going to work, and the coffee shop, and assigned them the idea that his father´s office is at the coffee shop, because that is where he sees his father going when he heads off to work. This is characteristic of symbolic meaning.
